With new, advanced and patented technologies, Eaton responds to customers’ rapidly changing requirements. Nine power supply problems at a glance How a UPS is part of the solution Eaton UPS systems offer protection against all nine typical power supply problems described below. They meet the requirements for assured power supply quality, energy distribution and power management for computer networks and data centers as well as for telecommunications, healthcare and industrial applications. Eaton product overview Eaton’s product range for protecting power supply quality comprises an extensive selection of power management solutions from a single source. It includes UPS systems, surge protection equipment, power distribution units (ePDUs), remote monitoring, testing devices, interconnect materials, housings, cabinets and services. Our portfolio for power supply quality is designed to customers’ specific requirements; comprehensive solutions are offered for both new systems as well as 0-4 Power supply problem 1 Power supply failure 2 Voltage dip 3 Voltage surges 4 Undervoltage (voltage drop) 5 Overvoltage 6 Electrical disturbance signals 7 Frequency deviations 8 Spikes due to switching operations 9 Harmonic distortion (harmonic waves) existing ones. With all its products, Eaton strives for continuous success in advancing technical innovation in order Eaton Wiring Manual 06/11 Total failure of supply network Can occur from a number of events: lightning strike, breaking of transmission lines, network congestion, accidents and natural disasters Temporary undervoltage Triggered by major power consumers being switched on, switching in the supply network, failure of grid facilities, lightning strike and power supply systems unable to meet requirements. In addition to possible device failure, hardware can also be damaged. Temporary voltage surge of more than 110 percent of the nominal value Can be caused by lightning strike and temporarily increase mains voltage to over 6,000 volts. A voltage peak almost always causes data losses or hardware damage. Reduced mains voltage for a period of between a few minutes to a few days Can occur if the mains voltage is intentionally reduced to reduce power during peak consumption periods or if the connected consumer load exceeds the supply capacity. Increased mains voltage for a period of between a few minutes and a few days Triggered by strong load reduction, major power consumers being switched off and other switching operations in the network. Hardware can be destroyed as a result. Disturbance signals with higher frequencies These can be triggered by electromagnetic interference (EMI) or radio frequency interference (RFI) from welding equipment, transmitting equipment, printers, thunderstorms etc. Instability of mains frequency These occur as a result of load variations, in particular in smaller generator installations. Frequency deviations can cause processes to fail, data losses, system breakdowns and damage to equipment. Temporary voltage dips Spikes of this kind last a very short time, within the nanosecond range. Distortion of sinusoidal waveform, usually caused by non-linear loads Switching mode power supplies, stepper motors, copiers and fax machines are examples of non-linear consumer loads. They can cause communication errors, overheating and hardware damage. to develop next-generation solutions.

Vacuum Technology Vacuum technology is at the heart of Eaton’s switching systems. Eaton has over 30 years of experience in applying vacuum technology in circuit-breakers and load-break switches. The use of this technology results in a maximally environmentally-friendly switchgear solution. combined heat and power plants. The design of the SVS and Xiria is based on a combination of vacuum and epoxy resin technology. There are a multitude of different types of switchgear suitable for every kind of application. With its compact dimensions and SF 6 -free design, SVS and Xiria are also the ideal solution for underground applications on infrastructure projects. Primary switchgear As its name says, primary switchgear is the first stage in transmitting electrical current from the supply network to the end customer. The importance of the strategic position of the substation and its switchgear within the system reflects the fact that layout, construction and operation must be designed for maximum availability and reliability. For this reason, Eaton’s portfolio includes the MMS – a compact stationary switchgear unit with single or double busbar – and PowerXpert ® UX, a switchgear unit with removable circuitbreakers, switches and contactors. Secondary switchgear Eaton has developed universal, modular secondary switchgear under the SVS and Xiria product series. It is suitable for use in supply networks, business premises, infrastructure projects, industrial applications and for structures relating to renewables such as wind farms and 0-6 Ring main units Electrical energy has become an indispensable element of modern society. A reliable and constant energy supply is increasing in importance every day. From the standpoint of energy companies and the industry, this means that the power distribution network must cope with ever increasing demand. It goes without saying that safety and operational reliability play a significant role. www.eaton.com www.eaton.com/electrical Eaton Wiring Manual What's new in this edition?

If the system is connected to the grid, the generated electricity is fed directly into it. Unlike grid independent systems the complicated temporary storage of electricity is not required, however, the generated DC current has to be converted to AC. 0-14 • a DC string protective device, • DC switch-disconnector • DC surge protection • PV inverter • Residual current device (RCD), • AC surge protection • and xComfort system (optional). The PV panels are connected in series (as a string) in order to provide the required input DC voltage for the inverter. Two or several strings are connected in parallel to increase the power of the system. For safety reasons, all electrical equipment must be isolated, protected and secured with switching devices which must likewise be protected with enclosures. All these important protective devices can be sourced directly from Eaton. Safe isolation, switching and protecting. In order to feed the generated electricity into the public grid or even to use it, inverters are required to convert the DC current of the solar cells in the AC current. The frequency and voltage values are adjusted to the grid parameters at hand. Also here, Eaton offers reliable protective and grid isolation devices such as inverters from 1500 to 4000 W for indoor use and from 4000 to 4600 W for outdoor applications. Eaton Wiring Manual 06/11 Eaton Wiring Manual Photovoltaics in residential buildings Converting solar energy efficiently Indoor use The ISG series with degree of protection IP43 is designed for indoor installation. Outdoor use The ISG series with degree of protection IP65 is designed for both indoor and outdoor applications. Specifications All power inverters are designed for ambient temperatures from -20 to +55 °C. Optimum operation is achieved at ambient air temperatures between 0 and +40 °C. Grid-connected power inverters from 1500 to 4600 W Each photovoltaic installation is as individual as the requirements of its user. Eaton therefore offers a complete line of single-phase power inverters from 1500 to 4600 W: • Suitable for moncrystalline and polycrystalline PV generators. • Maintenance free, highly reliable and very easy to install. • Integrated LCD display simplifies operation. • Optimum efficiency with maximum power point tracking (MPPT). • Fan-free thanks to natural convection cooling. • High performance compared to size. • Particularly quiet and low pollution operation. • Standard RS232 ENS interface in accordance with VDE0126-1-1/DK5940. • Compact elegant modern design. The power of the sun – used optimally The total output of a photovoltaic system not only depends on the total area of the PV panels, their alignment and the inclination angle of the modules. Components such as inverters play an important part in the efficiency of the system. Eaton inverters ensure you have the maximum output. Requirements, the DC isolation gap DC switch-disconnector The IEC 60364-7-712 standard stipulates the installation of a switch-disconnector between the PV generator and the inverter. Eaton offers enclosed and open switch-disconnectors for DC voltages up to 1000V. In accordance with the regulations of VDI 6012 they can be used as separate switching points, so that a faulty inverter can be completely de-energized safely. All switch-disconnectors switch two poles and are therefore also suitable for ungrounded systems. All switches are TÜV certified. 0-15 00 Eaton Wiring Manual 06/11 Eaton Wiring Manual Photovoltaics in residential buildings 00 Compact disconnectors for inverters Eaton offers both enclosed and open switch-disconnectors in its range. The open P-SOL switch disconnectors are designed for mounting in customized enclosures or inverters. They are mounted on 35-mm top-hat rails, and their terminals enable a connection to all commonly used cable types. Perfectly enclosed for outdoor installation Eaton's enclosed SOL switch-disconnectors are ready to fit and are therefore very easy to install. Variants for 2, 3, 4 or 8 strings are available for the most common connector types such as MC4 or metric glands. The enclosure is protected to IP65 and is suitable for outdoor installation. The lockable mechanism ensures safety during maintenance work. A pressure-equalizing element prevents the formation of condensation, preventing malfunctions caused by flashovers. 0-16 Fireman's switch – small investment, massive protection In the event of a house fire, the fire brigade can often only rescue persons or animals or prevent the fire spreading to neighboring buildings. This is due to the voltage of up to 1000 V generated by PV systems, which is still present after the inverter has been isolated. Rescue services are thus exposed to fatal risks when entering the building due to the possibility of damaged DC cables. Eaton's SOL30-SAFETY fireman's switch provides a solution here, and de-energizes the line from the solar modules to the inverter, this making safe any fire fighting activities. Although VDE 0100-7-712 stipulates the use of a DC isolator, it does not stipulate the location. The isolator is frequently integrated in the inverter so that the cable between this and the house terminal is safe, whilst a DC voltage of up to 1000V is still present in the solar modules and DC cables up to that point, with up to ~8A for each string. Eaton Wiring Manual 06/11 Eaton Wiring Manual Photovoltaics in residential buildings as well as having the ability to send trip indications via auxiliary contacts to thus avoid any losses in yield. A further feature of the DC string circuit-breaker is the variable tripping range for short-circuit currents: it reacts already from 1.05 … 1.3 times the residual current. Eaton offers both fuse switch-disconnectors as well as string circuit-breakers that can be combined easily with other components as required. Simple installation Fireman's switches are installed in direct proximity to the PV modules and inserted in the DC cable directly after the entry point into the building between the panels and the power inverter. The PV modules are disconnected automatically using undervoltage releases in the fireman's switch, when the AC voltage of the building is isolated either by the fire brigade or the local utility company or on site via a PV-OFF switch. DC-string protection If a PV installation has three or more strings, a string protection device using DC fuses or DC string circuit-breakers is recommended. These protect the PV panels from leakage and feedback currents that can occur on faulty strings, and prevent the feedback of good panels to panels with short-circuits. Compared to fuses, string circuit-breakers have the advantage that they are immediately operational again after the fault is rectified Fuse switch-disconnectors with integrated short-circuit protective device The task of the FCFDC10DISOL fuse switch-disconnector for the ASFLC10-SOL cylindrical fuse cartridges for fuse sizes 10 x 38 is to protect PV panels from short-circuit currents. A flash function can optionally be used to indicate a blown fuse. String circuit-breakers The Eaton PKZ-SOL string circuit-breakers are the fuseless alternative for protection against short-circuit currents. Its variable tripping range enables optional settings to the actual short-circuit current of a string. A thermal release responds already at 1.05 ... 1.3 times the current, whilst the magnetic release responds at 6 times the current. Non-enclosed string circuit-breakers are designed for installation in customized generator terminal boxes. 0-17 00 Eaton Wiring Manual 06/11 Eaton Wiring Manual Photovoltaics in residential buildings 00 DC surge protection Surge protective devices for PV applications The Eaton SPPT2PA surge arrester is specially developed for photovoltaic applications and offers protection from transient overvoltages that can occur through the indirect effect of lightning. Eaton offers types for both grounded and non-grounded systems in which the use of a spark gap ensures galvanic isolation. The units can be supplied pre-wired as ready to use connection units. Increasing building safety and comfort AC switching devices for buildings, such as miniature circuit-breakers and residual current devices offer maximum safety. Eaton products of the xPole series combine all functional, mounting and safety benefits: intelligent design solutions exclude the possibility of mounting faults. They even offer optimum safety for the end user: Personnel protection in the form of residual current devices and protection of the electrical installation in the form of overvoltage protection and MCBs. The portfolio is rounded off with an extensive range of intelligent switching devices such as remote switches, restart devices and others. 0-18 Digital residual current device FI With the development of digital technology a new level of precision was achieved that enables the avoidance of nuisance tripping. This can occur for example with permanent residual currents of electrical devices or temporary faults caused by storms. Here too, Eaton is also one step ahead: Eaton is the first company worldwide to offer a digital residual current device. The continuous status monitoring of the installation allows unwanted and annoying disconnections to be considerably reduced, thus guaranteeing optimum system availability. Three LEDs use the "traffic light" principle to indicate when a differential current has reached the 30% warning threshold. In this way, countermeasures can be taken in the installation before the situation gets worse. The installation user is thus provided with increased safety – with greater convenience. Combination switch The benefits of MCBs and RCDs combined in a single device – this is the Eaton combination switch. It saves space, whilst ensuring complete safety: reliable fire and personnel protection (30 mA) with enough space for flexible generous cabling. The surge current proof design prevents unwanted disconnection and selective types enable the selective disconnection of faulty system sections. Eaton Wiring Manual 06/11 Eaton Wiring Manual Photovoltaics in residential buildings Miniature circuit-breakers Regardless of whether plug terminal connections or screw terminals are required, Eaton has the right MCB for residential buildings and for industrial applications. Extensive accessories such as auxiliary contacts, shunt releases, restart devices and intelligent busbar solutions enable a host of applications and automation solutions. Distribution systems From the compact distribution board to the meter cabinet and the data network cabinet, Eaton offers a complete product portfolio. All applications can thus be covered for the infrastructure in residential and non-residential buildings as well as in the industrial sector. Surge protection Lightning strikes and overvoltages not only pose a risk for electrical installations but also for their operators. Eaton offers an extensive range of surge protective devices. Attachable auxiliary contacts also enable the monitoring of device functions. Wireless monitoring of PV installation and simple energy management Energy measuring sensor up to 16 A and Room Manager Convenient monitoring of electricity generation from your living room – modern home automation makes this possible. With xComfort, Eaton is offering the Room Manager with integrated energy management software (Energy Manager) for a powerful solution. The connection of the Eaton energy sensor with the inverter enables the electrical energy currently fed into the grid to be measured. This data is then transferred wirelessly to the Room-Manager which is installed in one of the living areas. Here, the user of the system can view values such as energy (kWh), power (kW), voltage (V) and amps (A) on a display. 0-19 00 Eaton Wiring Manual 06/11 Eaton Wiring Manual Photovoltaics in residential buildings 00 0-20 Eaton Wiring Manual 06/11 Eaton Wiring Manual Photovoltaics in residential buildings 00 Comfort, safety and energy management Wireless home automation enables lighting management, shade control, monitoring and danger warnings, as well as energy saving control concepts for heating, cooling and ventilation. Eaton's xComfort and Energy Manager thus offer transparency, comfort and safety combined: • Consumption control • Cost saving • Reduction of CO2 emission EU regulations stipulate that the actual energy consumption must be clearly visible to end consumers. The Eaton Room Manager covers this requirement by displaying and controlling the energy consumption of specific electrical or gas devices in the entire home. Entering the price per unit of measure makes it is possible to calculate the costs for a consumption cycle quickly and simply, for example for a bath or a washing machine cycle. More consumption and cost control is offered by a function that reads the history of the previous 24 hours right through to the last 12 months from the archive and shows it as a value or a trend on the display. It is also possible to output a warning message as soon as a user-defined limit value is exceeded. All this makes Eaton's energy management software a useful tool for identifying possible savings and reducing electricity costs for private system users. 0-21 Eaton Wiring Manual Eaton power distribution equipment 00 Eaton Wiring Manual 06/11 xEnergy – Safe energy distribution up to 5000 A The modular system consists of perfectly fitting function modules that are type tested to IEC/EN 61439 with Form 1 to Form 4 internal partitioning, and which take European and local (DIN, VDE, CEI, NF, UNE) installation practice into account. xEnergy provides the panel builder with a flexibly combinable product range for power distribution systems up to 5000 A.

Typical uses are as power distribution systems in utility buildings or as control panel enclosures in industry. This is where the xVtl can demonstrate the benefits of its rugged design. The xVtl is a stable, side-by-side mountable distributor made of sheet steel that is also best suited for stand-alone installation. It protects persons from coming into direct contact with conducting parts and even from possible electric shock, and reliably fends off damaging exterior influences. It carries out these functions according to the specific requirements, with protection degrees of IP40 or IP55. While the former is suited to diverse uses in functional buildings such as schools or hospitals, it is also recommended for harsher conditions such as wind energy systems, or in industry, in a foam-type polyurethane sealing design. Abrasion-proof protection against corrosion is guaranteed thanks to structured paint finish using a powder coating RAL 7035. 0-26 Overall, the technical design of the xVtlL complies with the IEC/EN 62208 and EN 60529 standards, as well as with Eaton Wiring Manual Eaton power distribution equipment IEC 60439-1, as long as it is used as a low-voltage energy distribution system.

The system offers protection from 6 to 100 kArms arc fault current. Detection of the arc faults is by light and current sensors. The evaluation unit responds when light and current signals are present. A tripping signal is applied to the quenching device and to the feeder circuit-breakers. The fault arc is quenched in less than 2 ms. The system can be put back into operation as soon as the fault is eliminated and the quenching device is renewed. b IZM ARC-EM ARC-EL3 ARC-AT c d a Current transformer b ARC-SL... linear light sensor c Electronic evaluation unit (slave) ARC-EL3 d Electronic evaluation unit (master) ARC-EM e ARC-AT quenching device 0-32 e ARCON® – Quenching device a Eaton Wiring Manual Eaton power distribution equipment Eaton Wiring Manual 06/11 Sheet steel wall-mounting enclosure CS with mounting plate The robust CS enclosure series with solid sheet steel is used wherever a particularly effective protection against direct contact with live parts or the protection of all installed equipment from harmful external influences is required. Thanks to its high degree of protection to IP 66 (UL/CSA Types 1, 12) with a continuous foam polyurethane gasket, water, oil or dirt is prevented from penetrating inside the enclosure. This makes the CS enclosure particularly suitable for subdistribution boards in control panels in industrial and utility buildings, as well as for machine building applications. The stable sheet steel enclosure meets the requirements of impact resistance category IK09 to EN 62262. Impact resistant metal locks provide additional safety. The hinge pins with quick change technology enable the door hinge to be replaced quickly since each metal pin can be 00 removed without any tools. Wall fixing brackets enable the switch cabinet to be mounted on a wall. The PHZ-A comfort rotary handle with locked position indication clearly shows on the outside whether the cylinder is in the opened or closed position. The comfort rotary handle can be retrofitted quickly, without the need to remove the standard lock - thus eliminating the need for the use of rotary levers. The galvanized sheet steel mounting plate with a maximum thickness of 3 mm ensures the safe installation of the switchgear and basic EMC protection. The CS enclosure can be turned through 180°, so that the cables can be fed in either via the top or bottom. The large flange plate openings allow the fitter more flexible handling. 0-33 Eaton Wiring Manual Eaton power distribution equipment 00 The foam gasket of the flange plate saves users the time required for gluing in foam rubber seals. Both flange and mounting plates are incorporated in the grounding concept, thus eliminating the need for an additional protective ground connection. Eaton Wiring Manual 06/11 Their powder coated surface provides an abrasion and corrosion resistant protection. As a special service, Eaton also offers individual solutions tailored to customer specifications. Compact distribution board for flush mounting and surface mounting KLV-U flush mounted compact distribution board The plastic enclosure suitable for cavity walls offers an outstanding level of stability whilst the flat design of the sheet steel door makes it inconspicuous in any room. An adjustment tolerance of up to 18 mm for compensating any unevenness in walls and plaster significantly simplifies flush mounting in wall openings. The zero and protective ground terminals are already prefitted. The KVL-U distribution board enclosure with protection class II and degree of protection IP30 are available in 1 to 4-row versions each with 12 + 2 module widths. The following door variants are available: Sheet steel door flat and super flat, plastic design door white and transparent. 0-34 BC-A surface mounted compact distribution board Wherever it is not possible to install in cavity walls, the rugged BC-A surface mounted compact distribution board protects the inside from mechanical damage and harmful environmental influences. In addition to degree of protection IP30, the unit meets the requirements of protection class II when used in conjunction with the back plate and the cover plate. In spite of its compact dimensions, up to 4 rows of 13 space units are available for each distribution board enclosure. The BC-A surface mounted compact distribution board comes standard with white and transparent doors. Eaton Wiring Manual Eaton power distribution equipment IVS service distribution system Eaton Wiring Manual 06/11 The IVS service distribution board up to 630 A is primarily used for the safe and economical power supply in industrial, building and commercial applications. 00 The range therefore includes wall and standard enclosures, each with protection to IP30 and IP54. The mounting space with an even division into standard 250 x 375 mm sections ensures a particularly clear design. Planning, ordering and mounting are thus simplified accordingly. • The link between the enclosure and the mounting units is the mounting system with insulated support brackets. The mounting system can be lifted out of the enclosure after the plates have been removed and the screws released. • A number of mounting units that are tailored to original Eaton switching and protective devices allow for time saving and simple mounting. • Insulated covers are used for protecting the mounting units from direct contact. Applicable standard for manufacturing is IEC EN 60439-1 "Type-tested low-voltage switchgear assemblies”. 0-35 Eaton Wiring Manual Eaton power distribution equipment 00 K terminal The connection terminal consists of a combination of several very stable terminal blocks. It is used for connecting two or several conductors.

The Eaton terminals are designed for copper strips or busbars as well as copper conductors. Each terminal pair is moulded in a plastic Duroplast shell. Each of the 6 sizes is available from stock as a 1-pole, 3-pole, 4-pole or 5-pole terminal combination. Accessories such as the transparent plastic cover, auxiliary conductor terminals or conversion kits also enable the creation of your own terminal variants. Eaton Wiring Manual Eaton power distribution equipment Eaton Wiring Manual 06/11 CI insulated distribution boards, totally insulated The assembly of the CI system demonstrates its flexibility. Whether as an individual enclosure, wall-mounted or floor standing distribution board of any size, the modular CI insulated distribution board up to 1600 A always offers the right solution in harsh ambient conditions. The modular system makes it easy to adapt to a wide range of conditions. • IP65 protection ensures protection from dust, humidity and water jets, • Pressure relief by means of liftable covers with spring-loaded enclosure bolts, 00 • "Total insulation" provides maximum personnel protection and operational safety. • Transparent neutral cover allows unrestricted view, • Lock mechanism actuated with cylinder lock or tool, • Floor standing distribution boards with base covers for routing, fixing or covering large cable cross-sections. Enclosed distribution boards are type-tested switchgear assemblies (TTA) in accordance with VDE 0660 part 500 or Type Tested Assemblies (TTA) to IEC 60439. 0-37 Eaton Wiring Manual Eaton power distribution equipment 00 Eaton Wiring Manual 06/11 SASY60i busbar system for the world market The SASY60i modular busbar system from Eaton is designed for effective power distribution in the control panel. Thanks to the innovative mounting technology feeder and outgoing circuit-breakers can be mounted quickly and compactly. SASY60i is safe and reliable. In conjunction with the latest generation of Eaton motor protective circuit-breakers and other circuit-breakers, the SASY 60i provides a universal, UL certified solution for switching, controlling, protecting and distributing energy. Together with the appropriate switching and protective devices, the busbar system is designed for worldwide use. 0-38 The larger clearances and creepage distances required in compliance with the UL 508A in America have been considered in the construction of the busbar components. When used in North America, the insulated bottom plate must be mounted under the system. Components approved for IEC such as NH fuse switch-disconnectors or D busbar mounting fuses can also suitable for perfectly matched fitting. As SASY60i requires few system components the new Eaton busbar system also reduces the stock-keeping and ordering required. These benefits naturally also apply to Eaton's SASY185i and SASY Compact busbar systems.

Typically the PLC is mounted in a control panel at a central position in the system. The control of the switchgear is carried out via special cables from the input and output terminals of the PLC for the control and return signals. With a decentralized configuration the switchgear and the remote input/output system are connected in the same way. The SmartWire-DT communication system replaces the control wiring previously required between the PLC inputs/outputs and the switching devices. In this way, the inputs/outputs of the PLC are relocated to the switching devices. Pluggable communication modules are used for this task. The communication is implemented via an 8-pole ribbon cable. Special device plugs are used for connecting the communication modules to the cable. The switchgear is supplied on the control circuit side by the connection cable. The SmartWire-DT system • reduces the time required for the control wiring and wiring test, • saves space in the control cabinet because cable ducts are unnecessary and • reduces the number of inputs/outputs required at the PLC. 1-2 The length of a SmartWire-DT network can be extended up to 600 meters. Up to 99 stations can be connected. You can use the SmartWire-DT technology flexibly. The connection via standard fieldbus systems (e.g. PROFIBUS, CANopen) enables SWD gateways to be used on the controller platforms of many manufacturers. Another option is the use of Eaton automation components (e.g. XV100 visualization system) with an integrated SmartWire-DT interface.

ZMR function Overload relay function: When the ZMR function is set, the contactor disconnects in the event of an overload. The PKE motor-protective circuit-breaker remains switched on (ON setting). The contact is reset with the MANUAL/AUTO function via PKE-SWD-32. 1-6 Eaton Wiring Manual 06/11 Switching, control, visualization SmartWire-DT communication system Overload relay function (ZMR) The ZMR function enables the motor to be switched off by the connected contactor in the event of an overload. To do this the PKE sends the switch off command for the contactor to the PKE-SWD-32 via the data cable of the PKE32-COM. The trip in response to a motor overload occurs if the thermal motor image of the PKE reaches 110 %. This value remains set until the thermal motor image has gone below the 100 % level and the operational readiness of the contactor is restored. The reclosing readiness of the contactor can be selected by the two manual and automatic operating modes of the ZMR function. The ZMR function can only be used in position "A" of the 1-0-A switch. In the event of a phase unbalance and activated ZMR function, the value of the thermal motor image is raised from 100 % to 110 % after a trip. ZMR Manual mode 11 In "manual" ZMR operating mode, the retriggering of the contactor must be acknowledged beforehand. ZMR Automatic mode In "automatic" ZMR mode, the contactor is ready to reclose immediately after the thermal image drops below 100 %. Danger! If the switch on command for the contactor is sent in "automatic" ZMR mode, the motor starts up automatically after the thermal motor image falls below 100 %. Never disconnect the communication link between the PKE-SWD-32 and the PKE trip block after an overload with the ZMR function activated, as this can cause the contactor to switch on if a switch command is present. The switched off contactor's readiness to reclose is restored when the value falls below 100 %. The ZMR function must not be activated with reversing starters since this operation does not ensure the disconnection of the second contactor in the event of an overload. 1-7 Eaton Wiring Manual 06/11 Switching, control, visualization SmartWire-DT communication system DOL starter with PKZ 11 The DOL starters are assembled from a PKZM0 and a DILM7 to DILM32 contactor. The connection to SmartWire-DT is implemented with the DIL-SWD-32-.. module. This is fitted directly on the contactor and connected via the SWD device plug with the SWD communication cable. 2 + 15V SWD4-8SF2-5 SWD4-8SF2 SWD4-8SF2 + 15V In addition to contactor control, two feedback signals can be sent to the SmartWire-DT system on each SmartWire-DT module for DILM. The SmartWire-DT module for DILM drives the contactor so that terminals A1-A2 must no longer be wired. The auxiliary contact X3-X4 is factory fitted with a link. If electrical interlocks are envisaged in the application, the link can be removed and a potential-free contact can be connected. Two feedback inputs to the programmable logic controller are provided at the three-pole terminal X0-X1-X2. If required, potential-free auxiliary contacts of the PKZ 1-8 → Figure, page 1-10 Reversing starter with PKZ The reversing starters are made up of a PKZM0 motor-protective circuit-breaker and two DILM7 to DILM32 contactors. A DIL-SWD-32-… SmartWire-DT module is fitted to each contactor and connected to the SWD communication cable via the SWD external device plug. In addition to contactor control, two feedback signals can be sent to the SmartWire-DT system on each SmartWire-DT module for DILM. SWD4-8SF2-5 1 motor protective circuit-breaker can be connected to these two feedback inputs (e.g. NHI-E-…-PKZ0 standard auxiliary contact, AGM2-…-PKZ0 differential trip-indicating auxiliary contact). The SmartWire-DT modules for DILM drive the contactors so that the connection terminals A1-A2 of the contactors need no further wiring, with the exception of the DILM12-XEV link. The auxiliary contact X3-X4 is factory fitted with a link. For the electrical interlocking of the two contactors this bridge is removed and the auxiliary breaker (contacts 21-22) of the other contactor is linked in as a potential-free contact. Two feedback inputs to the programmable logic controller are provided at the three-pole terminal X0-X1-X2. If required, potential-free auxiliary contacts of the PKZ motor protective circuit-breaker can be connected to these two feedback inputs (e.g. NHI-E-…-PKZ0 standard auxiliary contact, AGM2-…-PKZ0 differential trip-indicating auxiliary contact).

The SmartWire-DT system is not designed for the transfer of safety relevant signals. Using the configuration described below, the SmartWire-DT system can however be used for safety relevant switch offs. In an emergency the control voltage for the contactor coils can be switched off via the enabling paths of the safety relay. By using additional SmartWire-DT Power modules, contactor groups are made that can be switched off together in an emergency. This type of circuit can be used to create control systems up to PL c in accordance with EN ISO 13849-1 (PL = Performance Level). The safety relay in this example must be PL c or higher (e.g. ESR5-NO-41-24VAC-DC). → Figure, page 1-27 Feedback circuit The auxiliary contact integrated in the contactor is a mirror contact according to IEC/EC 60947-4-1. Using this contact the state of the main contacts can be reliably signalled. The mirror contact can be included into the feedback circuit of the safety relay so that the safety relay only gives a new enable signal when the contactor is open. 1-26 Measures for higher safety category In many applications control systems with a performance level of PL d or PL e (PL = Performance Level) to EN ISO 13849-1 are required. Control systems with PL d can be set up using an additional group contactor which is connected in series upstream of the motor feeders. The control voltage for the motor contactors as well as for the group contactor is switched off in an emergency via the safety relay. This redundant disconnection circuit enables the implementation of PL d control systems. The safety relay used must comply with PL d or higher to achieve this safety category (e.g. ESR5-NO-31-24VAC-DC).

This therefore lays down the technical measures for the reduction of hazards. The parts of machine control systems that handle safety tasks are defined as the “safety-related parts of control systems” (SRP/CS). Safety-related control systems comprise the entire safety function consisting of the input level (sensor), the logic (safety signal processing) and the output level (actuator). For reducing risks by means of SRP/CS, Eaton offers the right components with safety technology in accordance with the most stringent requirements stipulated in the safety standards EN 954-1, EN ISO 13849-1 and EN IEC 62061. The appropriate safety functions are used according to the application area and in compliance with the required risk reduction. Further information on the previous and the new international safety standards as well as circuit examples for a wide range of applications are provided in the latest version of the Eaton Safety Applications Technical Guide PU05907001Z-EN. The safety manual helps you by means of practical safety circuit examples and the associated calculations to determine safety performance in accordance with EN ISO 13849-1 and IEC 62061.

Eaton offers two logic series: • ESR5 Electronic safety relays • easySafety control relay suitable for safety circuits. Safety relays of the ESR5 series offer the optimum solution for each application with tailored safety functions. The internal logic of the safety relay monitors the wired safety circuits and activates the enable contacts in fault-free condition. The easySafety control relay offers a host of integrated safety relays in the form of safety function blocks in a single device, thus offering maximum flexibility in a considerable space saving design. easySafety is used for monitoring all typical safety devices and also implementing the control tasks required on the machine. Eaton Wiring Manual 06/11 The ESR safety relays or the easySafety control relay enable applications to be implemented that meet the most stringent safety requirements in accordance with international standards: • Category 4 to EN 954-1 • Performance level PL e acc. to EN ISO13849-1 • Safety Integrity Level SIL CL 3 according to IEC 62061 • Safety Integrity Level SIL 3 according to IEC 61508 Eaton ensures the required level of personal or process protection using the safety products approved by TÜV Rheinland – for both simple and complex machines. 1-31 11 Switching, control, visualization The way to the safe machine Monitoring a movable guard with ESR5 11 Moving guards such as safety doors, gates and flaps can be used to provide protection from accessible hazardous areas. The position of moving guards is detected with position switches or non-contacting contact sensors that are monitored and evaluated with a safety logic unit. A risk analysis supplies the necessary degree of risk reduction by the guard. Eaton Wiring Manual 06/11 Function The safety logic unit provides two separate input circuits for two-channel applications, which monitor the sensor (such as the position switch of an interlock device). After the input circuits are closed, the safety relay can be started by means of a reset button. This activates the enable and signal current paths and switches on the connected actuators. Positively driven auxiliary contacts of the actuators are used by the safety relay to diagnose possible safety states.

Machinery Directive 2006/42/EC stipulates however that every machine must be provided with a device for stopping in an emergency (Emergency stop). The degree of risk reduction by the Emergency stop device must be determined by means of a risk assessment. If the immediate disconnection of the power supply does not cause hazardous states, you can use an uncontrolled Stop function in accordance with Stop category 0 to EN ISO 13850. Eaton Wiring Manual 06/11 its interruption are implemented in the program. The two contactors drop out, and a restart is possible by pressing the START actuator. If the hazardous movement is stopped by pressing the Emergency-stop actuator S4, the enable for outputs QS1 and QS2 is removed and the contactors drop out. A restart is only possible after the Emergency-stop actuator is reset and enabled by pressing the RESET pushbutton. The drive can be braked actively by using output QS4.

Equipped with two changeover contacts which can be converted to two timing contacts 15-18 and 25-28 (A2-X1 linked) or one timing contact 15-18 and a non-delayed contact 21-24 (A2-X1 not linked). If the link A2-X1 is removed, only the timed contact 15-18 carries out the functions described below. Switching, control, visualization Timing relays Eaton Wiring Manual 06/11 Function 16 Function 11 On- and Off-delayed On-delayed A1-A2 15-18 t The actuating voltage Us is applied via an actuating contact to the terminals A1 and A2. After the set delay time the changeover contact of the output relay goes to the position 15-18 (25-28). Function 12 Off-delayed t A1-A2 Y1-Y2 B1 15-18 (25-28) After the supply voltage has been applied to the terminals A1 and A2, the changeover contact of the output relay remains in the original position 15-16 (25-26). If the terminals Y1 and Y2 in the DILET70 are linked by a potential-free N/O contact or, in the case of the ETR4-69/70 or ETR2-69, a potential is applied to B1, the changeover contact changes without delay to the position 15-18 (25-28). If the connection between the terminals Y1–Y2 is now interrupted, or B1 is separated from the potential, once the set time has elapsed, the changeover contact returns to it´s original position 15-16 (25-26). t t 11 A1-A2 Y1-Y2 B1 15-18 (25-28) The supply voltage Us is applied directly to the terminals A1 and A2. If the terminals Y1 and Y2 in the DILET70 are linked by a potential-free N/O contact, or in the case of of the ETR4-69/70 a potential is applied to B1, after a set time t the changeover contact goes to the position 15-18 (25-28). If the connection Y1-Y2 is now interrupted, or B1 is separated from the potential, the changeover contact goes back to it´s original position 15-16 (25-26) after the same time t. Function 21 Fleeting contact on energization A1-A2 t 15-18 (25-28) After the voltage Us has been applied to A1 and A2, the changeover contact of the output relay goes to position 15-18 (25-28) and remains actuated for as long as the set fleeting contact time. A fleeting pulse (terminals 1-2, 15-18) of defined duration is therefore produced from a two-wire control process (voltage on A25/A28) by this function. 1-37 Switching, control, visualization Timing relays Function 82 Pulse shaping 11 A1-A2 Y1-Y2 B1 15-18 (25-28) t After the supply voltage has been applied to A1 and A2, the changeover contact of the output relay remains in the rest position 15-16 (25-26). If the terminals Y1 and Y2 in the DILET70 are linked by a potential-free N/O contact, or in the case of the ETR4-69/70 or ETR2-69, a potential is applied to B1, the changeover contact changes without delay to the position 15-18 (25-28). If Y1–Y2 is now opened again, or B1 is is kept with the potential, the changeover contact remains actuated until the set time has elapsed. If, instead, Y1–Y2 remain closed or B1 is separated from the potential for longer, the output relay likewise changes back to its rest position after the set time. An output pulse of precisely defined duration is thus produced in the pulse shaping function, irrespective of whether the input pulse via Y1–Y2 or B1 is shorter or longer than the set time. Function 81 Pulse generating with fixed pulse A1-A2 t 0.5 s 15-18 (25-28) The actuating voltage is applied to the terminals A1 and A2 via an actuating 1-38 Eaton Wiring Manual 06/11 contact. After the set delay time has elapsed the changeover contact of the output relay goes to position 15-18 (25-28) and returns to it´s original position 15-16 (25-26) after 0.5 s. This function is therefore a fleeting pulse with a time delay. Function 22 Fleeting contact on de-energization t A1-A2 Y1-Y2 B1 15-18 (25-28) The supply voltage Us is present directly at A1 and A2. If the terminals Y1 and Y2 of the DILET70 that have been shorted (DILET-70 potential-free) at any time beforehand are opened again, or with ETR4-69/70 or ETR2-69 the contact B1 becomes potential-free again, the contact 15-18 (25-28) closes for the duration of the set time. Function 42 Flashing, pulse initiating t t t t A1-A2 15-18 (25-28) After the voltage Us has been applied to A1 and A2, the changeover contact of the output relay changes to position 15-18 (25-28) and remains actuated for as long as the set flashing time. The subsequent pause duration corresponds to the flashing time. Eaton Wiring Manual 06/11 Switching, control, visualization Timing relays Function 51 Star-delta Function 43 On-delayed Flashing, pause initiated t t t t t A1-A2 A1-A2 15-18 (25-28) 17-18 17-28 t tu 11 LED After the voltage Us has been applied to A1 and A2 the changeover contact of the output relay stays in position 15-16 for the set flashing time and after the duration of this time goes to position 15-18 (the cycle begins with a pause phase). If the actuating voltage Us is applied to A1 and A2, the instantaneous contact switches to position 17-18. After the set time duration the instantaneous contact opens; the timing contact 17-28 closes after a changeover time tu of 50 ms. On-Off Function Function 44 A1-A2 Flashing, two speeds A1-A2 OFF ON OFF A1-B1 t1 t2 t1 t2 t1 t2 15-18 Rel LED A1-B1 t1 t2 t1 t2 t1 t2 15-18 Rel LED After the voltage Us has been applied to A1 and A2 the changeover contact of the output relay goes to position 15-18 (pulse initiating). By bridging the contacts A1 and Y1 the relay can be switched to pause initiating. The times t1 and t2 can be set to different times. 15-18 (25-28) LED The On-Off function allows the operation of a control system to be tested and is an aid for example for commissioning. The Off function allows the output relay to be de-energized and it no longer reacts to the function sequence. The On function energizes the output relay. This function is dependent on the supply voltage being applied to the terminals A1/A2. The LED indicates the operating state.

With the new EMR range Eaton covers a large number of requirements: • general use, EMR...-I current monitoring relay • space saving monitoring of the rotation field, EMR...-F phase sequence relay • Protection against destruction or damage of single system parts, EMR…-(A)W(N) phase monitoring relay • safe recognition of phase failure, EMR...-A phase imbalance monitoring relay • enhanced safety by open-circuit principle, EMR...-N liquid level monitoring relay • increase of the operational safety, EMR...-R insulation monitoring relay EMR...-I Current monitoring relay The EMR-I current monitoring relay is suitable for the monitoring of AC as well as DC current. Pumps and drill machines can be monitored for underload or overload. This is possible due to the selectable lower or upper threshold limit. There are two versions each with three measuring ranges (30/100/1000 mA, 1.5/5/15 A). The multi-voltage coil allows universal use of the relay. The two auxiliary 1-40 changeover contacts allow for a direct feedback. Selected bridging of short current peaks By using the selectable response delay of between 0.05 and 30 s short current peaks can be bridged. Phase monitoring relay EMR...-W TheEMR...-W phase monitoring relay monitors the voltage as well as the rotation field rotation. This provides protection from the destruction or damage of individual system parts. The minimum undervoltage and also the maximum overvoltage can be set here easily, within a defined range to the required voltage. An on-delayed or off-delayed function can also be set. In the on-delayed position short voltage drops can be bridged. The off-delayed position allows for a fault storage for the set time. The delay time can be set between 0.1 und 10 s. The relay activates with the correct rotation field and voltage. After a drop-out the device does not reactive until the voltage exceeds a 5 % hysteresis. Eaton Wiring Manual 06/11 Switching, control, visualization EMR measuring and monitoring relays EMR...-F phase sequence relay detected even with a higher motor feedback and an overload of the motor can be prevented. EMR...-N liquid level monitoring relay With the only 22.5 mm wide phase sequence relay, portable motors, with which the rotation direction is important (e. g. pumps, saws, drills), can be monitored for correct rotation. This provides space in the switchboard thanks to the narrow width and protection against damage due to the monitoring of the rotating field. With correct rotating field the changeover contact releases the control voltage of the motor switching device. The EMR...-F500-2 covers the total voltage range from 200 to 500 V AC. EMR...-A phase imbalance relay The 22.5 mm wide EMR...-A phase imbalance relay is the correct protection device against phase failure. The motor is then protected against destruction. The EMR...-N liquid level monitoring relay is used mostly as dry running protection for pumps or for the level regulation of liquids. It operates with sensors that measure conductivity. One sensor is required for the maximum level and one sensor for the minimum level. A third sensor is used for earth potential. The 22.5 mm wide EMR...-N100 device is suitable for conductive liquids. It can be switched from level regulation to dry running protection. Safety is increased as in both cases the open-circuit principle is used. The EMR...-N500 liquid level monitoring relay has an increased sensitivity and is suitable for less conductive liquids. Due to an integrated pickup and drop-out delay of between 0.1 and 10 s moving liquids can also be monitored. As the phase failure is monitored on the basis of phase displacement, this can be 1-41 11 Eaton Wiring Manual 06/11 Switching, control, visualization EMR measuring and monitoring relays EMR...-R Insulation monitoring relay EMR...-AW(N) multifunctional three-phase monitors 11 EN 60204 “Safety of machines” provides increased operational safety by the monitoring of the auxiliary circuit for earth-fault using an insulation monitoring relay. This is the main application for the EMR...-R. There are similar requirements in medically used areas. An earth-fault is signalled via a changeover contact so that a fault can be cleared without expensive down time. The device has a selectable fault memory so that the fault must be acknowledged after it´s removal. The use of a Test button enables the device to be checked for correct operation at any time. AC or DC control voltage There is a device for AC and also DC. Therefore the total control voltage range is covered. Both devices have a multi-voltage source. This means that both AC and DC supplies are possible. 1-42 The multifunctional three-phase monitors provide the space saving monitoring of the rotation field with different functions.. These measure the phase parameters of phase sequence, phase failure, phase imbalance as well as undervoltage and overvoltage. Depending on device type, the threshold value for phase imbalance can be set between 2 to 15 %. The threshold values for undervoltage and overvoltage are adjustable or permanently set. The different options and set values are explained in the relevant instructional leaflet.

Connect therefore inductive loads to be switched via the easy outputs to a separate supply voltage, or use a suppressor circuit for motors and valves. Warning! Incorrect connection may lead to unwanted switching states. Analog signals are more sensitive to interference than digital signals, therefore the signal cables should be carefully routed and connected. • Use shielded twisted pair cables to prevent interference with the analog signals. • For short cable lengths, ground the shielding at both ends using a large contact area. If the cable length is more than around 30 m, grounding at both ends can result in equalization currents between the two grounding points and thus in the interference of analog signals. In this case, only ground the cable at one end. • Do not lay signal lines parallel to power cables. 1-53 11 Switching, control, visualization Engineering &Relay, MFD-Titan Eaton Wiring Manual 06/11 Connecting power supply and analog inputs for easy…AB device L 11 N ~ 0V EASY200-POW +12 V L01h F1 N01 h L N N I1 Notes With easy....

When I1 is actuated and reopened, the current flows via contact Q1 until I2 is actuated. 11 The latching (self-maintaining) circuit is used to switch machines on and off. The machine is switched on at the input terminals via N/O contact S1 and is switched off via N/C contact S2. S2 breaks the connection to the control voltage in order to switch off the machine. This ensures that the machine can be switched off, even in the event of a wire breakage. I2 is always closed when not actuated. A selfmaintaining circuit with open-circuit monitoring can alternatively be wired using the Set and Reset coil functions.

I2 inverts the break contact signal of S2 and only switches if S2 is activated in order to disconnect the machine or in the event of a wire breakage. Make sure that both coils are wired up in the correct order in the easy circuit diagram: first wire the S coil and then the R coil. This will ensure that the machine will be switched off when I2 is actuated, even if I1 is switched on.

The text display can display the following: RUNTIME M:S Line 1, 12 characters T1 :012:46 Line 2, 12 characters, a setpoint value or an actual value C1 :0355 Line 3, 12 characters, a setpoint value or actual value PRODUCED ST Line 4, 12 characters The setpoint values can be edited: • easy500 and easy700, two values • easy800, four values The text output function block D (D = Display, text display) functions in the circuit diagram like a normal marker M. Should a text be attached to a marker this would be shown at condition in the easy display when the coil is set to 1. For this easy must be in RUN mode and before the texts are displayed the Status display must be active. 1-92 D1 is defined as an alarm text and has therefore priority over text displays. D2 to D16/D32 are displayed when activated. When several displays are activated they are shown in succession every 4 secs. When a setpoint value is edited the corresponding display stays active until the value is transferred.

The beams are directed slightly over the front panel. The simultaneous interruption of several infra-red channels on the X and Y axis is used to indicate where the panel was touched in order to trigger the appropriate switch function. 11 Whether in machine or system building or in individual applications, an HMI (Human Machine Interface) or HMI-PLC (HMI with PLC functionality) simplifies operation and reduces the workload for the operator. Touch panels provide a clear, flexible menu navigation in any required language and enables the manufacturer to sell machinery worldwide with only one hardware and software solution. Touch panels with resistive and infra-red technology are primarily used. Eaton offers devices with both technologies. On the resistive touch panel, a conductive foil is stretched over the conductive screen surface. The foil is separated from the screen using several insulating pads. Only when a slight pressure is applied, does the foil touch the screen surface at this point and a current flows. A different current or resistance value is produced, based on the voltage divider principle according to where on the screen contact with the foil was made. The contact point is thus located unambiguously. The infra-red touch panels uses a light matrix in the infra-red range. 1-96 Eaton Wiring Manual 06/11 Switching, control, visualization HMI-PLC - Systematic visualization and control Touch-technology Infra-red Resistive Light permeability 100 % 70 – 85 % Operable with Fingers, gloves Fingers, gloves, touch pen Triggering of the function Without pressure (interruption of the light matrix) With slight pressure Display front Glass Plastic film Device front Level determined by the infra-red frame Fully flat Sensitivity to scratches No Yes Resistance to cleaning agent and chemicals High Average Use in humid atmospheres Yes Yes 11 Devices with display sizes from 3.5” to 19” are used in automation applications. Eaton offers device versions in plastic and metal. The front on the metal devices is either in aluminium or stainless steel. Front degree of protection: IP65 Most touch panels can also be used in portrait format (upright). 1-97 Eaton Wiring Manual 06/11 Switching, control, visualization HMI-PLC - Systematic visualization and control Engineering 11 ① ② ③ ④ ⑤ ⑥ a SD memory card (Secure Digital memory card) b USB device, page 1-98 c USB host, page 1-98 d Ethernet interface, page 1-99 e 24 V DC power supply POW and AUX (for SmartWire-DT slaves, page 1-99 f SmartWire-DT interface (only specific devices) page 1-100 g Onboard interfaces, depending upon the device: – RS232, page 1-100 – RS485, page 1-101 – CAN, page 1-102 – PROFIBUS-DP, page 1-104 h 24 V DC device supply, page 1-106 ⑦ ⑧ Rear view of a 7” resistive panel of the XV102 series with plastic housing ② USB device The USB device interface supports USB 2.0. • Cable – Only use standard USB cables with a shield. – Maximum cable length: 5 m ③ USB-Host The USB Host interface supports USB 2.0. • Cable – Only use standard USB cables with a shield. – Maximum cable length: 5 m 1-98 Eaton Wiring Manual 06/11 Switching, control, visualization HMI-PLC - Systematic visualization and control ④ Ethernet interface Supply voltage AUX: LINK ACT If there are any contactors or motor starters in the SWD topology, a 24 V DC voltage AUX must be additionally supplied as a control voltage for the contactor coils.

Remote I/Os can be found wherever remote signal processing is the key element of the automation concept. The XI/ON I/O system has the following essential features: • High modularity • Field busses: CANopen, PROFIBUS-DP, DeviceNet and Ethernet • Bus-independent, plug-in modules • Low wiring requirement • Effective diagnostics • Space and cost savings with ECO modules • Programmable CANopen coupling unit • Standard and ECO modules can be mixed The XI/ON I/O system provides an extensive range of digital and analog I/Os as well as technology modules: • XI/ON ECO gateways and ECO modules XI/ON ECO adds cost and space-optimized I/O modules and gateways to the XI/ON I/O system. The ECO gateways support the CANopen, PROFIBUS-DP and Ethernet bus systems. – ECO gateways with built-in bus termination resistors – Full compatibility with the standard XI/ON system – No base modules required – High channel density: (up to 16 DI/DO over 12.5 mm width) – Push-in spring-cage terminals – Multi-functional slices – Mini USB diagnostics interface • XI/ON Default gateways and standard modules The standard gateways support the CANopen, PROFIBUS-DP, DeviceNet and Ethernet bus systems. – Use of the pluggable I/O modules is possible regardless of the fieldbus used – Wiring implemented on base modules, fixed wiring – Hot-swapping of modules – Generation of diagnostics information for the higher-level controller – Up to 74 slice modules can be connected per gateway – Modules mechanical coding • Programmable CANopen coupling unit With the programmable CANopen gateway, PLC performance is now brought directly to the fieldbus terminal. The device is ideal for managing remote automation tasks and thus relieving the work load of a higher-level PLC. The serial onboard interface is used for programming onsite and as an interface for the I/Oassistant configuration and diagnostics tool. Alternatively this interface can also be 1-125 11 Switching, control, visualization Modular I/O system used as a free user interface. The gateway is programmed with XSOFT-CODESYS-2. 11 • Base modules for every requirement The base modules are used for connecting the fieldbus wiring for the standard XI/ON Eaton Wiring Manual 06/11 modules. They are available for 2-, 3- and 4-cable connections, as block or slice modules, either with spring-cage or screw terminals. Engineering I/Oassistant configuration and diagnostics tool The I/Oassistant is integrated in the XSOFT-CODESYS-2 software and offers interactive support in the entire planning and implementation of an XI/ON system. You choose the gateways, electronics and basic modules, as well as the appropriate accessories. The individual stations are then either configured online or offline. When everything is set to your requirements, you put the system into operation. I/Oassistant automatically generates a full parts list for your order. The I/Oassistant checks the station, reads process data, outputs values and visualizes the diagnostics data of the channels. In this way, you can also commission your station without the need for a higher-level controller and ensure that one section of the installation is functioning correctly. 1-126 Safety due to coding The pluggable modules also allow hot swapping for the fast and toolless exchange of modules. The mechanical coding of the modules prevents incorrect fitting.

Each instruction starts on a new line and contains an operator and one or several comma separated operands – depending on the type of operation. 11 Users of automation components such as machine and system builders are increasingly no longer satisfied with single solutions. This is why standards such as IEC 61131-3 have become established as manufacturer-independent standards for PLC programming. CoDeSys supports all programming languages described in the IEC-61131 standard. CoDeSys is based on a standard of 3S. Proven technical features, simple handling and a wide distribution of this software for programming automation components of different manufacturers guarantee its success. All Eaton controllers are programmed with the CoDeSys software. Programming can be carried out in different programming languages. These are divided into text-based or graphic-based languages. An identifier label followed by a colon (:) may be placed in front of an instruction. This is used for labelling the instruction which can then be used as a jump target. A comment must always be the last element of a line. Example: LD 17 ST lint (* comment *) GE 5 JMPC next LD idword EQ istruct.sdword STN test next: Structured Text (ST) Structured Text (ST) consists of a series of instructions that are arranged as in high level languages (IF...THEN...ELSE) or in loops (WHILE…DO). Example: IF value < 7 THEN WHILE value < 8 DO value := value + 1; END_WHILE; END_IF 1-130 Switching, control, visualization Software Eaton Wiring Manual 06/11 Graphic-oriented languages Sequential Function Chart (SFC) Sequential function chart (SFC) is a graphical language. It enables the timing of different actions within a program to be defined. Different step elements are used for this which are assigned to specific actions and which are controlled by so-called transition elements. 11 Example of a network in a sequential function chart: 1-131 Switching, control, visualization Software Eaton Wiring Manual 06/11 Ladder Diagram (LD) 11 Ladder diagram is a graphical programming language which closely follows the principle of an electrical circuit. On the one hand, ladder diagram is suitable for designing logical switch systems, on the other hand, it is also possible to create networks as in FBD. LD is therefore very good for controlling the calling of other blocks. Ladder diagram consists of a sequence of networks. A network is bordered on the left and right by a left and right vertical current path. A circuit diagram consisting of contacts, coils and connection lines is located in between. Example of a network in ladder diagram consisting of contacts and coils: Function Block Diagram (FBD) Function block diagram is a graphical programming language. It operates with a list of networks, in which each network contains a structure that may represent a logic and arithmetic expression, the calling of a function block, a jump or a return instruction. 1-132 Example of a network in a function block diagram: Switching, control, visualization Software Continuous function chart (CFC) The freely graphical function chart is based on function block diagram (FBD) but does not work like this with networks but with freely placable elements. This enables Eaton Wiring Manual 06/11 for example the implementation of feedback paths. Implementation example in freely graphical function block diagram editor: Integrated visualization The CoDeSys programming system also contains a visualization editor as well as the programming tool. This offers a clear advantage: which can be shown on a browser using TCP/IP (WEB visualization). Only one additional software package is required to visualize (i.e. for monitoring and operation) the data of a controller programmed in CoDeSys. Whilst the application is being developed, the user can already create visualization screens in the same user interface. The visualization integrated in CoDeSys can access the variables from the controller directly. For its HMI and HMI-PLCs Eaton offers an easy to learn project design environment that is nevertheless powerful and comprehensive – ideal for use in all machine and process-relevant applications in system and machine building. Galileo has a sector neutral design and offers seamless project design for all of Eaton's graphical HMI devices. If the controller has a display (HMI-PLC), this visualization can be displayed directly on the panel (target visualization). GALILEO interactive visualization tool Many controllers are now equipped with a web server. If required CoDeSys generates from the visualization data an XML description which is stored on the controller together with a Java applet and 1-133 11 Notes 11 1-134 Eaton Wiring Manual 06/11 Eaton Wiring Manual 06/11 Electronic motor starters and drives Page Drives engineering basic information 2-2 Soft starter basic information 2-9 Connection example DS7 2-26 DM4 connection example 2-44 Frequency inverter basic information 2-66 Connection example for M-Max™ 2-85 Rapid Link System 4.0 2-98 2-1 22 Eaton Wiring Manual 06/11 Electronic motor starters and drives Drives engineering basic information Drives egineering selection criteria 22 Each drive task requires a drive motor. The speed, torque and controllability of each motor must fulfill the requirements of the task. As a general rule, the application determines the drive. The drive motor most frequently used worldwide in industrial plants and large buildings is the three-phase asynchronous motor. Its robust and simple construction as well as its high degrees of protection and standard types are the main features of this inexpensive electric motor. Three-phase asynchronous motor Motor starting variants • Direct-on-line start ① In the simplest case the motor is connected directly with a contactor. The combination of motor protection and cable protection (fuse) is called a motor starter (MSC = Motor Starter Combination). By applying the full mains voltage to the motor windings, DOL starting may produce large starting currents which may result in troublesome voltage changes. Direct-on-line starting three-phase motors must not cause interference voltage changes in the public utility grid. This requirement is generally fulfilled if the apparent power of a three-phase asynchronous motor does not exceed 5.2 kVA or its startup current does not exceed 60 A. 2-2 With a mains voltage of 400 V and 8 times the starting current, this corresponds to a rated motor current of around 7.5 A and thus a motor rating of 4 kW. The motor rating denotes the mechanical output of the motor at the shaft. • Star-delta starter ② This is the most popular and commonly used starting method for motor ratings > 4 kW (400 V). • Electronic motor starter (EMS) and soft starter ③ These enable the soft and low-noise starting of the motor. This eliminates interference producing current peaks and jerks during switching. The startup and deceleration phase of the motor can also be time-controlled depending on the load. • Frequency inverter ④ This enables time-controlled motor starting, motor braking and operation with infinitely variable motor speeds. Depending on the application, different types of frequency inverters are used: – with the voltage/frequency control (U/f) or vector control for frequency-controlled motor operation, – with vector control or servo control for high speed accuracy and additional torque adjustment.

The standard connection is implemented via six screw terminals in the terminal box of the motor and with two types of circuit, the star connection and the delta connection, depending on the mains voltage. U1 V1 W1 W2 U2 V2 2-3 Eaton Wiring Manual 06/11 Electronic motor starters and drives Drives engineering basic information 22 The rotation direction of a motor is always determined by directly looking at the drive shaft of the motor (from the drive end). On motors with two shaft ends, the driving end is denoted with D (= Drive), the non-driving end with N (= No drive). The effect of inductance causes the rotation field and torque to be formed in the rotor winding. The speed of the motor thus depends on the number of pole pairs and the frequency of the supply voltage. The rotation direction can be reversed by swapping over two of the supply phases. Clockwise (FWD) Regardless of the circuit type and the type of three-phase asynchronous motor, the connections must be labeled, so that their alphabetical sequence (e.g. U1, V1, W1) corresponds with the order of the mains voltage sequence (L1, L2, L3) and causes the motor to rotate clockwise. 0 L1 L2 90° 180° L3 L1 360° 270° 120° 120° 120° On the three-phase asynchronous motor, three windings are arranged offset from each other by 120°/p (p = number of pole pairs). When a three-phase AC voltage with a 120° phase sequence is applied, this produces a rotation field in the motor. 2-4 Anticlockwise operation (REV) L1 L2 L3 L1 L2 L3 U1 V2 W3 U1 V2 W3 FWD = forward run (clockwise rotation field) REV = reverse run (anticlockwise rotation field active) Information on the rating plate The electrical and mechanical rating data of the motor must be stated on its rating plate (IEC 34-1, VDE 0530). The data on the rating plate describes the stationary operation of the motor in the area of its operating point (MN, e.g. at 400 V and 50 Hz). The operating data is unstable in the motor start phase. The following examples show the rating plates for two motors with a motor shaft output of 4 kW and the respective connection circuits on a three-phase AC network with 400 V and 50 Hz.

Eaton Wiring Manual 06/11 Electronic motor starters and drives Soft starter basic information Soft starters Soft starters are electronic devices for the soft starting of three-phase motors. Soft starters must comply with the product standard IEC/EN 60947-4-2. During the startup phase of a motor, a soft starter controls the power supply smoothly and continuously up to the rated value (ULN) by controlling the phase angle. This voltage control limits the starting current since the motor current behaves proportionally to the motor voltage. The resulting smooth torque increase enables the motor to be adapted to the load behavior of the motor. • Impacting of cog edges in the gearbox • Reduction of the water hammers in pipe systems • Slipping of V belts • Jitter with conveyor systems M/MN 3 2 MN 1 I / Ie ML 0.25 6 0.5 0.75 1 n/nN 5 4 3 2 IN 1 0.25 0.5 0.75 1 n/nN The mechanical components of this type of drive unit are therefore accelerated very smoothly. This has a positive effect on the lifespan, operating behavior and operating processes, and prevents any adverse effects such as: After a time controlled voltage change has elapsed (TOR = Top-of-Ramp), so-called bypass contacts can be used to bridge the phase angle control for the static continuous operation. The considerably lower transition resistance of the mechanical switch contacts compared to power semiconductors enables heat dissipation in the soft starter to be reduced and the lifespan of the power semiconductors to be extended. 2-9 22 Eaton Wiring Manual 06/11 Electronic motor starters and drives Soft starter basic information 22 ULN TOR U-Start t t-Start ULN = Mains voltage U-Start = Start voltage t-Start = Ramp time of the voltage change TOR = Top-of-Ramp (end point of the voltage control: U = ULN) Note The acceleration time of a drive with a soft starter always depends on the load and the breakaway torques. When commissioning this type of drive system, the required breakaway torque should be set first of all by means of the start voltage (U-Start) and then the shortest possible ramp time (t-Start) should be determined for the linear voltage change. As well as the time-controlled startup of a motor, the soft starter also enables a time-controlled reduction of the motor voltage and thus a controlled stopping of the motor. This type of stop function is 2-10 primarily used for pumps in order to prevent pressure waves (water hammer). Jerky movements and therefore the wear on drive chains and drive belts as well as bearings and gears can be reduced. Note The set ramp time for the deceleration (t-Stop) must be greater than the load-dependent uncontrolled deceleration time of the machine. Eaton Wiring Manual 06/11 Electronic motor starters and drives Soft starter basic information Control of the motor voltage U 22 U-Start t t-Stop t-Start The ratio of the overload current to the rated operational current, the total of the times for the controlled overload current, as well as the duty factor and start cycle form the overload current profile of a soft starter; this data is stated on the rating plate in accordance with IEC/EN 60947-4-2. Example 55A: AC-53a: 3-5 : 75-10 55A = Rated operational current of the soft starter AC-53a = Load cycle in accordance with IEC/EN 60947-4-2 Other overload cycles and operating frequencies can be calculated. Further information on this is provided in the relevant soft starter manual. Note The controlled deceleration presents a similar load on the power semiconductors in the soft starter as the start phase. If therefore the deceleration ramp is activated on a soft starter with a maximum of 10 permissible starts per hour, the number of permissible starts is reduced to 5 per hour (plus 5 stops within the same hour). 3 = 3-fold overcurrent at start (3 × 55 A = 165 A) 5 = Overcurrent duration in seconds 75 = Duty factor within the load cycle in % 10 = Number of permissible starts per hour 2-11 Eaton Wiring Manual 06/11 Electronic motor starters and drives Soft starter basic information Types Soft starters are usually divided into two types: 22 • Two-phase controlled, electronic soft starters for simple tasks: – Use is limited to small and medium rated motor (< 250 kW). – Simple handling with limited setting options and time controlled voltage ramps. – For simple applications where importance is placed on jerk-free operation in the starting phase. – They are an inexpensive alternative to the star-delta starter. – They can only be used in so-called In-Line configurations. 2-12 • Three-phase controlled, electronic soft starters for complex tasks: – For medium to high motor ratings up to 800 kW as compact devices – The devices are provided with an adjustable current limitation and integrated motor protection functions. – They have preset application characteristics and can be parameterized for optimizing the machine start functions. – Control inputs, signal contacts and optional fieldbus interfaces enable a wide range of communication options to be implemented. – They can be used in both In-Line and In-Delta configurations.

Danger! Dangerous voltage. Risk of death or serious injury. The power section of soft starters is formed with semi-conductors (thyristors). When a supply voltage (ULN) is present, there is also a dangerous voltage present at the output to the motor in the OFF/STOP state. This warning applies to all soft starter types.

For hybrid control devices and contactors, there is a risk of contact welding, for which the manufacturer must give maintenance instructions. Soft starters and coordination types to IEC/EN 60947-4-3 The following coordination types are defined in IEC/EN 60947-4-3, 8.2.5.1: The assigned short-circuit protective device (SCPD) must trip in the event of a short-circuit. If a fuse is used, this has to be replaced. This is part of the normal operation of the fuse, also for type 2 coordination. Type 1 coordination In type 1 coordination, the device must not endanger persons or the installation in the event of a short-circuit and does not have to be capable of continued operation without repairs or parts replacements. Type 2 coordination In type 2 coordination, the device must not endanger persons or the installation in the event of a short-circuit and must be capable of continued use without repairs or parts L1 L2 L3 PE Q1 Note Superfast semiconductor fuses must always be arranged directly in front of the power semiconductors (short cable lengths).

L1 L2 L3 PE There are two basic ways of protecting the three-phase motor from overload during operation: ① • Monitoring of current consumption (motor protection, overload relay or bimetal relay) • Direct temperature monitoring in the motor winding (PTC, thermistor) I> I> I> 1 L1 3 L2 5 L3 2 T1 4 T2 6 T3 ② a Motor-protective circuit-breaker (PKZ, PKE, NZM), disconnection with manual release b Overload relay (ZB, ZEB) – here in combination with a contactor c Overload relay (ZB, ZEB) for indication of the thermal overload d Thermistor, PTC or positive temperature coefficient protection in the motor winding with external indication relay (EMT) ③ Note M 3~ M1 The combination of the current monitoring motor protection variants ①, ② or ③ with the temperature monitoring variants ④ is also called full motor protection. ④ Note After a motor protective device has tripped, the soft starter and the protective device cannot be switched on again until it has cooled down. The reset depends on the temperature. 2-19 22 Eaton Wiring Manual 06/11 Electronic motor starters and drives Soft starter basic information Parallel connection of several motors to a single soft starter 22 You can also use soft starters to start several motors connected in parallel. This does not, however, allow the startup behavior of the individual motors to be controlled. Notes • The current consumption of all connected motors must not exceed the rated operational current Ie of the soft starter. • Each motor must be protected from thermal overload individually, e.g. with thermistors and/or overload relays (F11, F12) . Alternatively, motor-protective circuit-breakers (Q11, Q12) can also be used. • It is advisable to use this circuit type only with motors of a similar rating (maximum deviation: one rating size). Problems may arise during starting if motors with significant rating differences (for example 1.5 kW and 11 kW) are connected to the output of a soft starter. The lower-rated motors may not be able to reach the required torque due to the relatively high ohmic resistance of their stators. During the startup these require a higher voltage. • The last motor must not be switched off in operation since the resulting voltage peaks may cause damage to the electronic components in the soft starter and thus to its failure. 2-20 Eaton Wiring Manual 06/11 Electronic motor starters and drives Soft starter basic information L1 L2 L3 22 F1 Q1 Q11 F3 L1 L2 L3 Q21 T1 T2 T3 F12 F11 M1 F11, F12: F3: Q1 or F1: Q11 Q12 M 3 M2 I> I> I> M 3 Motor protection (overload relay) or motor-protective circuit-breaker (Q11, Q12) Superfast semi-conductor fuses (optional, additionally to Q1 and F1) Short-circuit and cable protection 2-21 Eaton Wiring Manual 06/11 Electronic motor starters and drives Soft starter basic information Using soft starters with three-phase slipring motors 22 When upgrading or modernizing older installations, contactors and rotor resistors of multistage three-phase stator automatic starters can be replaced with soft starters. This is done by removing the rotor resistors and assigned contactors and short-circuiting the slip rings of the motor’s rotor. The soft starter is then connected into the feeder. The smooth starting of the motor can then be implemented. → Figure, page 2-23 Notes • Slip ring motors develop a high starting torque with low starting current. They can thus be started at the rated load and this must be taken into account when selecting a soft starter. The soft starter cannot replace the rotor resistors in every application. • Depending on the type of motor, it may be necessary to keep the last resistor group permanently connected to the slipring rotor terminal (K-L-M). 2-22 Q1: Cable and motor overload protection or F1: Cable protection and F2: Overload protection required (thermistor, bimetal relay) if the soft starter (Q21) does not include this function.

This reactive power can be compensated by means of capacitors (Cx) ① (improved power factor cos ϕ). WARNING The output of a soft starter must not be connected to any capacitive loads (capacitors) ②. This would damage the soft starter. If capacitors are to be used for reactive power compensation and thus to improve the power factor, they must be connected to the mains side of the soft starter ③. If the soft starter is used together with an isolating or main contactor (Q11), the capacitors must be disconnected from the soft starter (Q12) when the contactor contacts are open. 2-24 The following figure ③ shows a safe arrangement. The compensation capacitors are switched via a capacitor contactor (Q12). The capacitor contactor is controlled via the TOR (Top-of-Ramp) signal of the soft starter. The capacitors are disconnected from the mains during the critical start and stop times. Note In networks with electronically controlled loads (e.g. soft starters), the compensation devices must always be connected with a series inductance.

Bypass circuit for emergency operation In pump applications the bypass contactor is often required to provide emergency operation capability. A service switch is used to select between soft starter operation and DOL starter operation via a bypass contactor (Q22). This is used to fully isolate the soft starter. In this case, it is important that the output circuit is not opened during operation. The interlocks ensure that a switchover is only possible after a stop.

Additional plant-specific settings can be defined with an optional keypad. This includes, for example, the three-phase AC power controller mode. In this mode three-phase resistive and inductive loads (heaters, lighting systems, transformers) can be controlled with the DM4. Both open-loop and – with measured value feedback – closed-loop control are possible. Instead of the keypad, intelligent interfaces can also be used: • RS232/RS485 serial interface (configuration with PC software) • PROFIBUS-DP fieldbus connection The DM4 soft starter provides the most convenient method of implementing soft starting. In addition to phase failure and motor current monitoring, the motor winding temperature is evaluated through the built-in thermistor input, so that the soft starters do not require additional external components, such as motor protective relays. Note The optional superfast semiconductor fuses (F3) for type 2 coordination can be used from size 2 (from 85 A) in the housing of the DM4 soft starter.

The soft starter is enabled only when a High signal is present at the terminal. The soft starter cannot be operated without the enable signal. In the event of wire breakage or interruption of the signal by an Emergency-Stop circuit, the regulator in the soft starter is immediately blocked and the power circuit disconnected, and after that the ”Run“ relay drops out. Normally the drive is always stopped via a ramp function. When the operating conditions require an immediate de-energization, this is effected via the enabling signal. Warning! You must in all operating conditions always first stop the soft starter (”Run” relay scanning), before you mechanically interrupt the power conductors. Otherwise a flowing current is interrupted – thus resulting in voltage peaks, which in rare cases may destroy the thyristors of the soft starter. = E2: Q21: S1: S2: S1 S2 K1 2-50 K1 K1 Q21 E2 39 Emergency switching off Digital input Soft starter (E2 = 1 + enabled) Off On Eaton Wiring Manual 06/11 Electronic motor starters and drives DM4 connection example Linking the overload relay into the control system We recommend using an external overload relay instead of a motor-protective circuit-breaker with built-in overload relay. This allows controlled ramping down of the soft starter through the control section in the event of an overload.

The direct opening of the power lines may cause overvoltage and destruction of the soft starter’s semi-conductors. E2 a The signalling contacts of the overload relay are incorporated in the on/off circuit. In the event of a fault, the soft starter decelerates according to the set ramp time and stops. b The signalling contacts of the overload relay are incorporated in the enable circuit. In the event of a fault, the soft starter’s output is immediately de-energized. The soft starter switches off but the mains contactor remains on. In order to switch off the mains contactor, a second contact of the overload relay must be incorporated in the on/off circuit. 39 Emergency switching off Off On Soft starter (E2 = 1 → enabled) 2-51 22 Eaton Wiring Manual 06/11 Electronic motor starters and drives DM4 connection example With separate contactor and overload relay Actuation Q1 K1 I> I> I> S2 Q11 S1 K1 F2 K1 F3 E2 Q21 39 L 3L3 2L2 1L1 a ~ N = M1 2-52 M 3~ 6T3 4T2 T1 – Thermistor + Thermistor Q21 2T1 22 L1 L2 L3 N PE Standard connection For isolation from the mains, either a mains contactor upstream of the soft starter or a central switching device (contactor or main switch) is necessary.

The DM4 soft starter also allows operation in an in-delta connection. The antiparallel thyristors are connected directly in series to the individual motor windings. Advantages (compared with in-line connection): • Inexpensive since the soft starter only has to be designed for approx. 58 % (1/√3) of the rated current – particularly with motor ratings > 30 kW and when replacing star-delta starters. • For the same motor rating the required soft starter rating is reduced. 2-56 Disadvantages (compared with in-line connection): • As in a star-delta circuit, the motor must be connected with six conductors. • The DM4 soft starter overload protection is active only in one line so that additional motor protection must be fitted in the parallel phase or in the supply cable. The motor can be protected for example via thermistors. Notes • The voltage of the motor winding must match the rated voltage. For a 400 V mains voltage the motor must therefore be marked with 400 V/690 V. • The soft starter can also be bridged in the in-delta connection for continuous operation with a bypass contactor (see page 2-60). This is actuated via TOR (Top-of-Ramp).

Thus, the motor is directly connected with the mains. Advantage: • The soft starter’s heat dissipation is reduced to the no-load dissipation. • The limit values of radio interference class ”B“ are adhered to. The bypass contactor is now switched to a de-energized state and can therefore be designed to utilization category AC-1. If an immediate voltage switch-off is required in the event of an emergency stop, the bypass contactor must also switch the motor load. In this case a design to utilization category AC-3 is required.

L1 L2 L3 PEN L1 L2 L3 N PE Connection and operation on asymmetrically grounded networks such as phase grounded delta networks (USA) or non-grounded or resistively grounded (> 30 Ω) IT networks are only permissible with restrictions and require additional engineering measures. The standardized rated operating voltages of the utility companies fulfil the following conditions at the point of transfer to the consumer: • Maximum deviation from the rated voltage (ULN): ±10 % • Maximum deviation in the voltage symmetry: ±3 % • Maximum deviation from the rated frequency: ±4 % A further voltage drop of 4 % in the consumer networks is permissible in relation to the lower voltage value (ULN -10 %) of the supplying mains voltage. The power supply voltage at the consumer can therefore have a value of ULN -14 %. In ring meshed networks (as used in the EU) the consumer voltages (230 V / 400 V / 690 V) are identical to the power supply voltages of the utility companies. In star networks (for example in North America/USA), the stated consumer voltages take the voltage drop from the utility company’s infeed point to the last consumer into account.

Each device not only exerts interference on other devices but is also adversely affected by it. This occurs as a result of galvanic, capacitive and/or inductive coupling or through electromagnetic radiation. The border between line-conducted interference and radiated interference is around 30 MHz. Above 30 MHz the lines and cables act like antennas and radiate the electromagnetic waves. The electromagnetic compatibility (EMC) for variable speed drives is implemented in accordance with product standard IEC/EN 61800-3. This covers the entire drive system (PDS = Power Drives System) from the mains end supply to the motor, including all components and cables. This type of drive system can also consist of several individual drives. The generic standards of the individual components in a PDS compliant with IEC/EN 61800-3 do not apply. These component manufacturers, however, must offer solutions that ensure standards-compliant use. In Europe, maintaining the EMC Directive is mandatory. A declaration of conformity (CE) refers always to a ”typical” power drives system (PDS). The responsibility to comply with the legally stipulated limit values and thus the provision of electromagnetic compatibility is ultimately the responsibility of the end user or system operator. Measures must be taken to remove or minimize emission in the associated environment. It must also be ensured that the immunity of the devices or systems is increased.

For the protection of persons, AC/DC-sensitive residual current devices (RCD Type B) are required in addition. Contactors are used for the on/off switching of the mains voltage. Mains chokes suppress any current harmonics and peaks and limit the inrush current (link circuit capacitors). RFI suppression filters attenuate high frequency electromagnetic emissions from devices. They ensure that the EMC limit values for conducted interference specified in the applicable product standards are observed (frequency inverters). Frequency inverters enable the infinitely variable speed control of three-phase motors. A braking resistor converts the frequency inverter’s regenerative braking energy into heat. The frequency inverter must be equipped with a brake chopper, which connects the braking resistor parallel to the internal DC link. Motor reactors • Compensate the capacitive capacitive currents, • Reduce current ripple and the motor’s current change noise, • Attenuate the retroaction on parallel connection of several motors. Sinusoidal filter • Smoothen the output voltage sinusoidally, • Reduce motor noise through du/dt reduction, and thereby increase the motor insulation’s lifespan, • Reduce the leakage currents to allow better motor performance at improved EMC values. Shielded motor cables attenuate emitted and conducted high-frequency emissions within the limit values specified in the applicable product standard (EMC).

All conducting metallic enclosure sections must be electrically connected to the earth potential. For EMC compliance, the important factor is not the cable’s cross-section, but its surface, since this is where high frequency current flows to earth. All earth points must have a low impedance, be highly conductive and routed directly to the central earth point (potential equalization bar or star earth). The contact points must be free from paint and rust. Use galvanized mounting plates and materials. For an EMC-compliant installation, observe the following instructions. These enable electrical and magnetic interference fields to be limited to the required levels. The necessary measures work only in combination and should be taken into consideration at the engineering stage. To subsequently modify an installation to meet EMC requirements is possible only at considerable additional cost. Measures for EMC-compliant installation are: • Earthing measures, • Shielding measures, • Filtering measures, • Chokes They are described in more detail below.

Cables between frequency inverters and motor must be shielded. However, the shield must not be considered a replacement for the PE cable. Four-wire motor cables are recommended (three phases plus PE). The shield must be connected to earth (PES) at both ends with a large-area connection. Do not connect the shield with pigtails. Interruptions in the shield, such as terminals, contactors, chokes, etc., must have a low impedance and be bridged with a large contact area. To do this, sever the shield near the module and establish a large-area contact with earth potential (PES, shield terminal). Free, unshielded cables should not be longer than about 100 mm. Example: Shield attachment for maintenance switch ① PES ② PES ③ a Metal plate (e.g. MSB-I2) b Earthing terminal c Maintenance switch 2-78 MBS-I2 4.2 x 8.2 ⌀ 4.1 ⌀ 3.5 Note Maintenance switches at of frequency inverter outputs must be operated only at zero current. Control and signal lines must be twisted and may be double-shielded, the inner shield being connected to the voltage source at one end and the outer shield at both ends. Eaton Wiring Manual 06/11 Electronic motor starters and drives Frequency inverter basic information ② The motor cable must be laid separately from the control and signal lines (> 30 cm) and must not run parallel to any power cables. ① Note Inside control panels also cables should be shielded if they are more than 30 cm long. ≧ 300 mm (≧ 11.81”) a Power cables: network, motor, DC link circuit, braking resistor b Signal cables: analog and digital control signals Example of shielding control and signal cables: Standard connection of a frequency inverter with setpoint potentiometer R11 (M22-4K7), control signals for clockwise and anticlockwise rotation (FWD, REV) and ZB4-102-KS1 mounting accessory 1 AI 0V REV FWD +24 V 15 +10 V 2 ≦ 20 m PES 3 2 Cu 2.5 mm PE M4 ZB4-102-KS1 PES 4K7 R11 M M REV FWD 2-79 22 Eaton Wiring Manual 06/11 Electronic motor starters and drives Frequency inverter basic information 22 Filtering measures Radio interference filters and line filters (combinations of radio interference filter and mains choke) protect against conducted high-frequency interference (noise immunity) and reduce the frequency inverter’s high-frequency interference which is transmitted through or emitted from the mains cable, and which must be limited to a prescribed and legal level (emitted interference). Nowadays, filters are frequently integrated in the frequency inverter or should be installed in close proximity of the frequency inverter. When using externally installed RFI filters, the connection cable between the frequency inverter and filter must be kept short (≦ 30 cm). 2-80 Note The mounting surfaces of frequency inverters and radio interference filters must be free from paint and must have good HF conductivity.

To prevent dangerous voltages, all components (frequency inverter, RFI filter, motor, shielded motor cables) in the PDS must be earthed. As the leakage currents are high-frequency interference sources, the earthing connections and cables must have a low impedance and large contact surfaces. L1 L2 L3 N PE 2-82 F F K RCD The residual current device on the frequency inverter must be of type B as sinusoidal AC and pulsed DC residual currents may occur. With leakage currents ≧ 3.5 mA, EN 60335 states that one of the following conditions must be fulfilled: • The protective conductor must have a cross-section ≧ 10 mm2, • The protective conductor must be open-circuit monitored, or • An additional protective conductor must be fitted. T L1 L2 L3 R2 S2 T2 M U V W L1 L2 L3 M 3∼ Eaton Wiring Manual 06/11 Electronic motor starters and drives Frequency inverter basic information Mains chokes Fitted on the frequency inverter’s input side, chokes reduce the current-dependent mains feedback and improve the power factor. This reduces the current harmonics and improves the mains quality. The use of mains chokes is especially recommended when several frequency inverters are connected to a single mains supply point and when other electronic devices are also connected on the network. Single-phase chokes A reduction of the mains current interference is also achieved by installing DC chokes in the frequency inverter’s DC link. This eliminates the need for mains chokes. Motor chokes With long motor cables or the parallel connection of several motors, motor chokes ① are used at the output of the frequency inverter. Three-phase chokes They also enhance the protection of the power semiconductors in the event of an earth fault or short-circuit, and protect the motors from excessive rates of voltage rise (> 500 V/μs) resulting from high pulse frequencies. ① Q11 Q12 Q13 F1 F2 F3 U1 V1 W1 M1 M 3 ˜ M2 U1 V1 W1 M 3 ˜ U1 V1 W1 M3 M 3 ˜ 2-83 22 Eaton Wiring Manual 06/11 Electronic motor starters and drives Frequency inverter basic information Sinusoidal filter Sinusoidal filters are a combination of choke and capacitor (low pass filter). ① They improve the sinusoidal shape of the frequency inverter output voltage, thus reducing the noise and the temperature rise of the motor. 22 Advantages of the sinusoidal filter: ② SFB400/… • Long shielded motor supply cables possible – max. 400 m on supply voltages up to 240 V +10 % – max. 200 m on supply voltages up to 480 V +10 % • Extended lifespan – like that of a mains-operated motor • Low noise generation of the motor • Low motor temperature rise • Reduced du/dt values (< 500 V/μs) Disadvantages of a sinusoidal filter: • Up to 30 V voltage drop • Operation only with fixed pulse frequency possible 2-84 Eaton Wiring Manual 06/11 Electronic motor starters and drives Connection example for M-Max™ M-Max™ product features ② ① 22 ③ ④ ⑩ ⑨ ⑧ BACK RESET HOA OK I ⑦ ⑤ ⑥ Designations on M-Max™ a Fixing holes (screw fastening) b Release (dismantling from mounting rail) c Cutout for mounting on mounting rail (DIN EN 50022-35) d Interface for fieldbus connection modules (optional, MMX-NET-XA) e EMC installation accessories f Power section terminals g Cover flap of control signal terminals and microswitches h Interface for PC connection module MMX-COM-PC (Option) i Keypad with 9 control buttons j Display unit (LCD) 2-85 Eaton Wiring Manual 06/11 Electronic motor starters and drives Connection example for M-Max™ 22 Functions A comprehensive range of protection functions allow safe operation and the protection of frequency inverter, motor and application.

They are especially suitable for applications where simple operation and profitability are important. The characteristics-controlled voltage/frequency (U/f) control already allows a wide range of applications even with the default settings: from simple pump and fan drives, standard packaging applications right through to the operation of multiple motors in horizontal transportation and conveying. With sensorless vector control, an individual drive can also be used in demanding applications, in which a high torque and concentricity in the lower speed range are vital, for example in the plastics and metal industries, the textile, paper and printing industries or in crane and elevator systems. Rated operating currents from 1.4 to 14 A allow the operation of standard 4 pole asynchronous motors in an assigned performance range of : • 0.25 to 2.2 kW at 230 V (single-phase mains connection), • 0.25 to 2.2 kW at 230 V (three-phase mains connection), • 0.37 to 5.5 kW at 400 V (three-phase mains connection). 2-88 Instructions • For UL®-compliant installation and operation, the mains side switching devices must allow for a 1.25 times higher input current. • Mains contactors shown here take into account the rated operating current ILN of the frequency inverter at the input without a mains choke.

They are available with or without keys, turn-releasable, non-illuminated, illuminated with standard LEDs or with mechanical switch position indication (green/red) in the center of the actuator element. The self-monitoring contact elements ensure extensive operational safety; even with a faulty installation or after excessive force is used for actuation. As well as the emergency-off NC contact, the modular contact elements feature an integrated second contact for querying the mechanical connection to the emergency stop actuator element. The contact elements are available for front or bottom fixing, for single or dual-channel safety circuits up to SIL 3 in accordance with IEC 62061 or Performance Level PL e to EN ISO 13849-1. 3-8 Eaton Wiring Manual 06/11 An optional illuminated ring enables emergency-stop/off pushbutton actuators on a machine or a plant to be made more conspicuous. Even in darkened environments, the position of these pushbutton actuators is clearly indicated. The illuminated ring also clearly indicates the operating state from a considerable distance. When tripped, for example, it is possible to activate three separately controllable LED rows as a running light.

Here, the term positive opening is defined as follows: “The execution of a contact separation as the direct result of a predetermined motion of the keypad of the switch via non-spring operated parts (e.g. not dependent on a spring )“. PRÜFZ ERT In addition to these requirements, LS...ZB position switches offer additional manipulation safety by means of an operating head which can rotate but cannot be removed. Certification All Eaton safety position switches are certified by the employers' liability insurance Association or by the Technical Monitoring Service (TÜV), Rheinland. ERT “Position switches for safety functions must be designed so that the safety function cannot be bypassed manually or simple tools.” Simple tools are: pliers, screwdrivers, pins, nails, wire, scissors, penknives etc. Positive opening is an opening movement by which it is ensured that the main contacts of a switch have attained the open position at the same time as the keypad assumes the Off position. Eaton position switches all meet these requirements. BG 33 Eaton safety position switches have been specially designed for monitoring the position of protective guards such as doors, hinged flaps, shrouds and protective guards.

Two high-speed and bounce-free PNP switching outputs enable high switching frequencies. 33 The position switch is overload as well as conditionally short-circuit proof and has snap-action switching performance. This ensures a defined and reproduceable switching point. The operating point lies in the range from 0.5 to 5.5 mm (as supplied = 3 mm). Adjustment to a new operating point is carried out as follows: adjust fix Move the plunger from the original to the new switch position. For this purpose, press the setting pushbutton for 1 s.

Analog, mechanically actuated position switches directly linked with the world of automation Analog position switches LSE-AI (4 to 20 mA) and LSE-AU (0 to 10 V) represent another innovation in electronic position switches. Using them, it is now possible for the first time to monitor the actual position of a flue gas valve or an actuator continuously. The actual position is converted in analog fashion into voltage (0 to 10 V) or current (4 to 20 mA) and then continuously signalled to the electronics. Even objects of varying sizes or thicknesses, such as brake shoes, can be scanned and the results processed further.

The objects are detected through an electromagnetic field. 33 Assembly parts With the ability to detect at close range, inductive proximity sensors are very useful for precision measurement and inspection applications. How an inductive sensor works Inductive sensors create an invisible high frequency oscillation field. When metal objects are brought into this field, this oscillating field is affected. Each sensor has a specific sensing range switch point so that metal target detection is very accurate and repeatable. If a metal object is brought into the field created by the sensor, this is interrupted and causes a reduction in the current flowing through the sensor coil (eddy current damping). The detector circuit senses this change and sends a signal via the sensor output. A metal object, or target, enters the sensing field. The sensor coil is a coil of wire typically wound around a ferrite core. If you could see the electromagnetic field created by it, it would be cone shape. The target will pass through this field. The ferrite core 3-30 Pilot devices Sensors – Functionality shapes the field and the size of the coil determines the sensing range. The resonance circuit creates a high frequency oscillation of the electromagnetic field (between 100 Hz and 1 MHz). If a metal object is located in the field, this causes a change in the magnetic field oscillation. This change creates an eddy current which dampens the signal fed back to the sensor coil. The detector circuit senses the change and switches ON at a particular set point (amplitude). This ON signal generates a signal to the solid-state output. The output circuit remains active until the target leaves the sensing field. The oscillator responds with an increase in amplitude, and when it reaches the setpoint value, the detector circuit switches OFF. The output returns to its normal state.

To use this table, multiply the sensing distance of the device by the factor given below. 3-31 33 Pilot devices Sensors – Functionality Eaton Wiring Manual 06/11 Capacitive sensors Capacitive sensors are designed to detect both metallic and nonmetallic targets. They are ideally suited for liquid level control and for sensing powdered or granulated material. 33 Operation of the capacitive sensors Capacitive sensors operate using a capacitor. This consists of two metal plates that are separated by an insulating dielectric material. The function of this type of sensor is based on dielectric capacitance, which is the ability of a dielectric to store an electrical charge. • Capacitor ① ③ ② The distance between the plates determines the ability of the capacitor to store an electrical charge. a Plates b Switch c Dielectric If an object is put into the electrical field. the capacitance of the capacitor changes. This change is used to implement the on/off switch function. When this principle is applied to the capacitive sensor, one capacitive plate is part of the switch, the enclosure (the sensor face) is the insulator. The target is the other “plate”. Ground is the common path. Capacitive proximity sensors can detect any target that has a dielectric constant greater than air. Liquids have high dielectric constants. Metal also makes a good target. 3-32 Pilot devices Sensors – Functionality Eaton Wiring Manual 06/11 • Capacitive sensor Capacitive sensors consist essentially of four basic elements: solid and liquid materials is greater than that for air. • Sensor (Dielectric) • Resonance circuit • Detector circuit • Output circuit. As an object approaches the sensor, the dielectric constant of the capacitor changes. The oscillator circuit’s vibration begins when feedback capacitance is detected. This is just the opposite in the inductive proximity sensor, where the vibration is damped when the target is present. Objects made of non-conductive materials affect the active surface of a capacitive proximity switch in the same way. The coupling capacitance is increased. Materials with a high dielectric constant achieve great switching distances. Notes When scanning organic materials (wood, grain, etc.) it must be noted that the attainable switching distance is greatly dependent on their moisture content. (εWater = 80!) Effects Capacitive sensors are activated both by conductive as well as non-conductive objects. Metals achieve the greatest switching distances due to their high conductivity. Derating factors for various metals, such as are necessary with inductive sensors, need not be taken into account. Actuation by objects made of non-conductive materials (insulators): When an insulator is brought between the electrodes of a capacitor, the capacitance rises relative to the dielectric constant e of the insulator. The dielectric constant for all 3-33 33 Eaton Wiring Manual 06/11 Pilot devices Sensors – Functionality Influence of environmental conditions As can be seen from the following diagram, the switching distance Sr is dependent on the dielectric constant εr of the object to be monitored. 33 Metal objects produce the maximum switching distance (100 %).

Due to the high dielectric value of water, the fluctuations with wood can be significant.

An object is detected when it passes between the LED and photodetector, interrupting the light beam. Optical sensors use light to detect the presence or absence of an object. The main advantages of optical sensors are contactless sensing of objects and greatly extended sensing ranges. Let’s look at how an optical sensor works. ① ② ③ ④ ⑤ ⑥ ⑤ ⑩ ⑨ ⑧ a Power supply: Feeds the sensor circuit with a regulated DC voltage. b Modulator: generates pulses to cycle amplifier and LED at desired frequency. c Source current amplifier d LED e Lens f Target object or reflector g Photodetector: Either a photodiode or a phototransistor device, selected for a maximum sensitivity at the source LED’s emitted light wave-length. Both the source LED and the detector have protective lenses. When the sensor picks up the ⑦ light, it sends a small amount of current to the detector amplifier. h Detector Amplifier: Blocks current generated by the background light. It also provides amplification of the signal received to a usable level, and sends it through to the demodulator. i Demodulator: Sorts out the light thrown out by the sensor from all other light in the area. If the demodulator decides the signals it receive are okay, it signals the output. j Output: Performs switching routine when directed to do so by the demodulator. 3-35 33 Pilot devices Sensors – Functionality Eaton Wiring Manual 06/11 Detection methods Operating Mode Description Operating Mode Light barriers A source unit in one location sends a light beam to a detector unit in another location. An object is detected when it passes between the source unit and the detector unit, interrupting the light beam. Reflected-light beam Light source and receiver are located in the same unit. If a target moves in front of the optical sensor, a reflector reflects the light beam directly back to the receiver. Background rejection (Perfect Prox) Target 33 Detector Source Polarisation reflex sensor Target Retroreflector Reflex Sensor 3-36 Description Target Reflex Sensor Light source and receiver are located in the same unit.

They are used in large quantities for the indirect control of motors, valves, clutches and heating equipment. In addition to the simplicity which they offer in project engineering, panel building, commissioning and maintenance, the high level of safety which they afford is a major factor in their favor. 55 Security The contactor relay contacts themselves constitute a considerable safety feature. By design and construction they ensure potential isolation between the actuating circuit and the operating circuit, in the de-energized state, between the contact input and output. All DIL contactor relays have double-break contacts. The Employers' liability insurance association demands that, for control systems of power-driven metalwork presses, the contacts of contactors must be interlocked and opposing. Interlocking means that the contacts are mechanically connected to one another such that N/C contacts and N/O contacts can never be closed simultaneously. At the same time, it is necessary to ensure that the contact gaps are at least 0.5 mm over the lifespan, even when defective (e.g. when a contact is welded). The contactor relays DILER and DILA fulfil this requirement. Contactor relays DIL Two contactor relay series are available as a modular system: • Contactor relays DILER, • Contactor relays DILA. Modular system The modular system has many advantages for the user. The system is formed around basic units, which are equipped with additional functions by means of modules. Basic units are intrinsically functional units, consisting of an AC or DC drive and four auxiliary contacts. 5-2 Modules having auxiliary functions Auxiliary contact modules having 2 or 4 contacts. The combination of N/O and N/C contacts is according to EN 50011. The auxiliary contact modules of the contactors DILEM and DILM cannot be snapped onto the basic device to prevent duplication of terminal markings e.g. contact 21/22 on the basic device and 21/22 on the add-on auxiliary contact module. The DILA and DILM7 to DILM38 contactors of the DILA-XHIR22 auxiliary contact are available specially for switching the smallest signals for electronic applications. Eaton Wiring Manual 06/11 Contactors and relays Contactor relays The system and the Standard European Standard EN 50011 “Terminal markings, distinctive numbers and reference letters for certain contactor relays” has a direct bearing on the use and application of the modular system. There are various types, which the Standard differentiates between by means of reference numbers and reference letters, depending on the number and position of the N/O and N/C contacts in the device, and their terminal markings. Ideally devices with the reference letter E should be used. The basic devices DILA-40, DILA-31, DILA-22 as well as DILER-40, DILER-31 and DILER-22 comply with the E version. Example 1 DILA-XHI04 Example 2 DILA-XHI13 For 6 and 8 pole contactor relays, the “E” version means that four N/O contacts must be arranged in the lower/rear contact level.

As suppressor circuits the following are connected on the front: DILA The DC operated contactors DILER and DILA have an integrated suppressor circuit. On the top positioned terminals A1–A2 of the contactor DILER the following accessories are connected to limit the relay coil switch off breaking voltage peaks: • RC suppressors • Free-wheel diode suppressors • Varistor suppressors Suppressor circuit Electronic equipment is nowadays being increasingly used in combination with conventional switching devices such as contactors. This equipment includes programmable logic controllers (PLCs) timing relays and coupling modules, whose operation can be adversely affected by disturbances from interactions between all the components. One of the disturbance factors occurs when inductive loads, such as coils of electromagnetic switching devices, are switched off. High cut-off induction voltages can be produced when such devices are switched off and, under some circumstances, can destroy adjacent electronic devices or, via capacitive 5-4 coupling mechanisms, can generate interference voltage pulses and thus cause function disturbances. Since interference-free disconnection is impossible without an accessory, the coils may be connected to a suppressor module, depending on the application. The advantages and disadvantages of the various suppressor circuits are explained in the following table.

For every motor rating between 3 kW and 900 kW (at 400 V) there is a suitable contactor available. Equipment features • Magnet system Due to the new electronic operation the DC contactors from 17 to 72 A have a sealing power of only 0.5 W. Even for 170 A is only 2.1 W necessary. • Accessible control voltage connections The coil connections are on the front of the contactor. They are not covered by the main current wiring. • Can be controlled directly from the PLC The contactors DILA and DILM to 38 A can be controlled directly from the PLC. • Integrated suppressor DC With all DC contactors DILM a suppressor is integrated in the electronics. • Plug-in suppressor circuits AC With all AC contactors DILM up to 170 A a suppressor can be simply plugged in on the front when required. • Conventional control of contactors DILM185A to DILM2600 via coil terminals A1-A2. • Additional actuation of contactors DILM250 to DILH2600: – Directly from a PLC via terminals A3-A4 – By a low-power contact via terminals A10-A11. • Conventional control of contactors DILM250-S to DILM500-S via coil connections A1-A2. There are two coil terminals (110 to 120 V 50/60 Hz and 220 to 240 V 50/60 Hz). • All contactors up to DILM170 are finger and back-of-hand proof to VDE 0160 Part 100. Additional terminal covers are available from DILM185 onwards. • Double-frame terminal for contactors DILM7 to DILM170 With the new double frame-clamp the cable connection area is not limited by the screw. They give total security with varying cross sections and have protection against incorrect insertion to ensure safe connection. • Integrated auxiliary contact The contactors up to DILM32 have an integrated auxiliary contact as N/O or N/C contact. • Screw or spring-cage terminal The contactors DILE(E)M and DILA/DILM12, including the corresponding auxiliary contacts, up to 2000 A, are available with screw or spring terminals. • Contactors with screwless terminals They have spring-cage terminals in the mains current circuit as well as for the coil connections and auxiliary contacts. The shake proof and maintenance free spring-cage terminals can terminate two conductors each of 0.75 to 2.5 mm2 with or without ferrules. • Connection terminals Up to DILM72 the connection terminals for all auxiliary contacts and coils as well as for main conductors can be tightened with a Pozidriv screwdriver size 2. For contactors DILM80 to DILM170 Allen screws are used. 5-15 55 Contactors and relays Contactors DIL 55 • Mounting All contactors can be fitted on to a mounting plate with fixing screws. DILE(E)M and DILM up to 72 A can also be snapped on to a 35 mm top-hat rail to IEC/EN 60715. • Mechanical interlock With two connectors and a mechanical interlock an interlocked contactor combination up to 170 A can be achieved without extra space requirement. The mechanical interlock ensures that both connected contactors cannot be simultaneously be operated. Even with a mechanical shock the contacts of both contactors cannot close simultaneously. In addition to individual contactors, complete contactor combinations are also available: • DIUL reversing contactors from 3 to 75 kW/400 V • SDAINL star-delta starters from 5.5 to 132 kW/400 V DC operated contactors The market for DC operated contactors is growing due to the increasing use of electronics. Whilst AC operated contactors were used 20 years ago with additional resistors and specially wound DC coils with a lot of copper were used till recently, the next quantum leap has started. Electronic components are now in use for the drives of DC operated contactors. The xStart contactor series DILM7 to DILM225A has been particularly optimized in the development of DC actuated contactors. The DILM17 to DILM225A DC 5-16 Eaton Wiring Manual 06/11 operated contactors are no longer switched on or off in the conventional way using a coil but by means of an electronic unit. The integration of electronics in the contactor drives makes different technical features possible which enable the contactors to offer outstanding performance in their daily use. Universal voltage coils The DILM17 to DILM225A DC operated contactors cover the entire DC control voltage range with only 4 control voltage variants. Rated actuation voltage RDC24 24 - 27 V DC RDC60 48 - 60 V DC RDC130 110 - 130 V DC RDC240 200 - 240 V DC Contactors and relays Contactors DIL Voltage tolerance Contactors are built in compliance with the IEC/EN 60947-4-1 standard. The requirement for operational safety even with small mains supply fluctuations is implemented with the reliable switching of contactors at between 85 to 110 % of the rated control circuit voltage. The DC operated DILM17 to DILM225A contactors now cover an even wider range in which they switch reliably. They allow reliable operation between 0.7 x Ucmin and 1.2 x Ucmax of the rated actuation voltage. The greater voltage tolerance than stipulated by the standard increases operating safety even with less stable mains conditions. Suppressor circuit Conventionally operated contactors generate voltage peaks at the coil to current change dI/dt which can have a negative effect on other components in the same actuating circuit. To prevent damage, contactor coils are often connected in parallel with additional suppressor circuits (RC suppressors, varistors or diodes). Eaton Wiring Manual 06/11 When using DC operated contactors from Eaton in the project design, the issue of transient voltage surge suppression in control circuits is therefore unnecessary since all DC operated contactors are free of system disturbance or are provided with a suppressor circuit. Contactor dimensions The electronic circuit offers the coil a higher inrush consumption and reduces this after the closing operation to the required sealing power. This enables the AC and DC operated contactors to be implemented with the same dimensions. When designing AC and DC operated contactors for a project, the additional problem of different mounting depths is eliminated so that the same accessories can be used. Thanks to their electronics, the DC actuated contactors DILM17 to DILM225A switch without any effect on the network. An additional suppressor is therefore unnecessary since the coils do not generate any external overvoltages. The other DILM7 to DILM15 DC operated contactors have a built-in suppressor circuit. 5-17 55 Eaton Wiring Manual 06/11 Contactors and relays Contactors DIL Pick-up and hold-in power The electronic circuit on the DILM17 to DILM225A DC operated contactors controls their operation. A suitably high power is provided for the pickup to ensure the reliable switching of the contactor. A very low sealing power is required for holding the contactor. The electronics only provides this power. Rated power 1) Contactor 55 Power consumption Pickup Sealing 7.515 kW DILM17 DILM25 DILM32 DILM38 12 W 0.5 W 18.537 kW DILM40 DILM50 DILM65 DILM72 24 W 0.5 W 3745 kW DILM80 DILM95 90 W 1.3 W 5590 kW DILM115 DILM150 DILM170 149 W 2.1 W 90110 kW DILM185A DILM225A 180 W 2.1 W 1) AC-3 at 400 V For project design, the reduced sealing power also means a considerable reduction in the heat dissipation in the switch cabinet. This allows side by side mounting of the contactors in the switch cabinet. 5-18 Contactors and relays Contactors DIL Applications The three-phase motor dominates the electric motor sector. Apart from individual low-power drives, which are often switched directly by hand, most motors are controlled using contactors and contactor combinations. The power rating in kilowatts (kW) or the current rating in amperes (A) is therefore the critical feature for correct contactor selection. Physical motor design results in that rated currents for the same rating sometimes differ widely. Furthermore it determines the ratio of the transient peak current and the starting current to the rated operational current (Ie). Eaton Wiring Manual 06/11 The auxiliary contact of the contactor DILM can be used as mirror contact to IEC/EN 60947-4-1 Appendix F to show the condition of the main contacts. A mirror contact is an N/C contact that cannot be simultaneously closed with the N/O main contacts. Other applications • Contactors for capacitors for power factor correction DILK for 12.5 to 50 kvar/400 V. • Lighting contactors for DILL lighting systems for 12 to 20 A/400 V (AC-5a) or 14 to 27 A/400 V (AC-5b). Switching electrical heating installations, lighting fittings, transformers and power factor correction installations, with their typical individual characteristics, increases the wide range of different uses for contactors. The operating frequency can vary greatly in every application. The difference can be, for example, from less than one operation per day up to a thousand operations or more per hour. Quite often, in the case of motors, a high operating frequency coincides with inching and plugging duty. Contactors are actuated by hand or automatically, using various types of command devices, depending on the travel, time, pressure or temperature. Any interrelationships required between a number of contactors can easily be produced by means of interlocks via their auxiliary contacts. 5-19 55 Eaton Wiring Manual 06/11 Contactors and relays Overload relays Z Motor protection using Z thermal overload relays Overload relays are included in the group of current-dependent protective devices. They monitor the temperature of the motor winding indirectly via the current flowing in the supply cables, and offer proven and cost-efficient protection from destruction as a result of: 55 • Non starting, • Overload, • Phase failure. Overload relays operate by using the characteristic changes of shape and state of the bimetal when subjected to heating. When a specific temperature is reached, they operate an auxiliary switch. The heating is caused by resistances through which the motor current flows. The equilibrium between the reference and actual value occurs at various temperatures depending on the magnitude of the current. Tripping occurs when the response temperature is reached. The tripping time depends on the magnitude of the current and preloading of the relay. Whatever the current, the relay must trip out before the motor insulation is endangered, which is why EN 60947-4-1 states maximum response times. To prevent nuisance tripping, minimum times are also given for the limit current and locked-rotor current. Phase failure sensitivity Overload relays Z offer, due to their design, an effective protection against phase failure. They have phase failure sensitivity to IEC 60947-4-1 and VDE 0660 part 102 and therefore can also provide protection for Ex e motors (→ following diagrams). Trip bar Differential bar S Differential travel 97 95 97 95 97 95 98 96 98 96 98 96 Normal operation (no fault) Normal operation (no fault) a Trip bridge b Differential bar c Differential travel 5-20 Three-phase overload three-phase overload One phase drops out (2-phase load) One phase drops out Contactors and relays Overload relays Z When the bimetallic strips in the main current section of the relay deflect as a result of three-phase motor overloading, all three act on a trip bar and a differential bar. A shared trip lever switches over the auxiliary contact when the limits are reached. The trip and differential bars lie against the bimetallic strips with uniform pressure. If, in the event of phase failure for instance, one bimetallic strip does not deflect (or recover) as strongly as the other two, then the trip and differential bars will Eaton Wiring Manual 06/11 cover different distances. This differential movement is converted in the device by a step-up mechanism into a supplementary tripping movement, and thus accelerates the tripping action.

M ON Like the ZEB, overload relays with electronic wide-range overload protection operate with a larger current transfer ratio.

These are combined with an evaluation unit so that separate arrangement of the current sensor and the evaluation unit is possible. The current sensor is based on the Rogowski principle from the measurement technology. The sensor belt has no iron core, unlike a current transformer, therefore it doesn´t become saturated and can measure a very wide current range. Due to this inductive current detection, the conductor cross-sections used in the load circuit have no influence on the tripping accuracy. With electronic overload relays, it is possible to set higher current ranges than is possible with electromechanical thermal overload relays. In the ZEV System, the entire protected range from 1 to 820 A is covered using only an evaluation unit. The ZEV electronic motor-protective system carries out motor protection both by means of indirect temperature measurement via the current and also by means of direct temperature measurement in motors with thermistors. 5-26 Indirectly, the motor is monitored for overload, phase failure and unbalanced current consumption. With direct measurement, the temperature in the motor winding is detected by means of one or more PTC thermistors. In the event of excessive temperature rise, the signal is passed to the tripping unit and the auxiliary contacts are actuated. A reset is not possible until the thermistors cool to less than the response temperature. The built-in thermistor connection allows the relay to be used as complete motor protection. In addition, the relay protects the motor against earth faults. Small currents flow out even in the event of minor damage to the motor winding insulation. These fault currents are registered on an external core-balance transformer which adds together the currents in the phases, evaluates them and reports fault currents to the microprocessor in the relay. By selecting one of the eight tripping classes (CLASS) allows the motor to be protected to be adapted from normal to extended starting conditions. This allows the thermal reserves of the motor to be used safely.

The evaluation unit has a multi-voltage version, which enables all voltages between 24 V and 240 V AC or DC to be applied as supply voltage. The devices have monostable behavior; they trip out as soon as the supply voltage fails. In addition to the usual N/C contact (95-96) and the N/O contact (97-98) for overload relays the motor protection relay ZEV is equipped with a programmable N/O contact (07-08) and a programmable N/C contact (05-06). The above mentioned, usual contacts react directly via thermistors or indirectly via the current, to the detected temperature rise of the motor, including phase failure sensitivity. achieved and the tripping delays are constant over the entire setting range. If the motor current imbalance exceeds 50 %, the relay trips after 2.5 s. The accreditation exists for overload protection of explosion proof motors of the explosion protection “enhanced safety” Ex e to guideline 94/9/EG as well as the report of the German Physical/Technical Bureau (PTB report) (EG-Prototype test certificate number PTB 10 ATEX 3007). Further information can be found in the manual MN03407008Z-DE/EN “Motor protection system ZEV, overload monitoring of motors in Ex e areas”. The programmable contacts can be assigned to various signals, such as • Earth-fault, • Pre-warning at 105 % thermal overload, • Separate indication of thermistor tripping, • Internal device fault. The function assignment is menu-guided using a display. The motor current is entered without tools using the function keys, and can be clearly verified on the display. In addition the display allows a differential diagnostics of trip reasons, and therefore a faster error handling is possible. Tripping in the event of a three-pole balanced overload at x-times the set current takes place within the time specified by the tripping class. The tripping delay in comparison with the cold state is reduced as a function of the preloading of the motor.

The NZM1 to NZM4 or N1 to N4 can be used as backup motor-protective circuit-breakers/circuit-breakers or switch-disconnectors when fitted with a NZM…-XUVL undervoltage releases. Operating principle 55 The CMD (Contactor Monitoring Device) monitors the main contacts of a contactor for welding. It compares the contactor control voltage with the state of the main contactors and indicates this reliably with a mirror contact (IEC EN 60947-4-1 Ann. F). If the contactor coil is de-energized and the contactor does not drop out, the CMD trips the backup circuit-breaker, motor-protective circuit-breaker or switch-disconnector via an undervoltage release. The CMD also monitors the functioning of the internal relay using an additional auxiliary make contact of the monitored contactor. For this the auxiliary make and break contact is positively driven. The break contact is designed as a mirror contact. Approved switchgear combinations To ensure the functional reliability of the entire unit, consisting of contactor, circuit-breaker and CMD, the CMD is only approved for use with specific contactors as well as motor-protective circuit-breakers/circuit-breakers/or switch-disconnectors. CMD can be used for monitoring the welding of all DILEM and DILM7 to DILH2000 contactors. All auxiliary 5-36 Applications These combinations are used in safety-oriented applications. Previously, the series connection of two contactors was recommended with circuits of safety category 3 and 4. Now one contactor and the contactor monitoring device is sufficient for safety category 3. The CMD contactor monitoring relay is used for emergency-stop applications in compliance with EN 60204-1. It can also be used in the American automotive industry. In this sector there is a demand for solutions that reliably detect the welding of the motor starters and disconnect the motor feeder safely. The CMD is approved as a safety module by the German employers' liability insurance association. It also has UL and CSA approval for the North American market.

The basic device is without overload release, but equipped with short-circuit release. This circuit-breaker is used for protection of resistive loads where no overloading is to be expected. These protective switches are also used in motor-starter combinations with and without reclosing lockout, where an overload relay or a thermistor overload relay is used as well. Transformer-protective circuit-breakers 66 PKZM0-…-T The transformer-protective circuit-breaker is designed for protecting transformer primaries. The short-circuit releases in the types from 0.16 A to 25 A are permanently set to 20 x Iu. The response ranges of the short-circuit releases are higher here than with motor-protective circuit-breakers in order to cope with the even higher inrush currents of idling transformers without tripping. The overload release in the PKZM0-T is set to the rated current of the transformer primary. All the PKZM0 system accessories can be combined with the PKZM0-T. 6-6 PKZM0-…-…C The PKZM0 features a version with springloaded terminals. A version with springloaded terminals on both sides, and a combined version which features springloaded terminals on the outgoer side only can be chosen. The conductors can be connected here without ferrules. The connections are maintenance-free. Motor-protective circuit-breakers MSC Motor starters – description Eaton Wiring Manual 06/11 Motor starter combinations The MSC motor-starter combinations are available up to 32 A. Motor starters up to 16 A consist of a PKZM0 or PKE motor-protective circuit-breaker and a DILM contactor. Both are connected by a tool-less mechanical connection element. Furthermore, a plug-in electrical connector is used to establish the connection with the main circuit wiring. The PKZM0 or PKE motor-protective circuit-breaker and the DILM contactors up to 16 A are provided with the relevant interfaces for this purpose. The MSC motor-starter combinations from 16 A consist of a motor-protective circuit-breaker PKZM0 or PKE and a contactor DILM. Both are fitted to a top-hat rail and mechanically and electrically interconnected by a connector element. The MSC is available as a MSC-D DOL starter and as a MSC-R reversing starter. The combinations of PKZM4 or PKE65 with the proven DILM contactors are available for motor ratings over 15 kW/400 V. 66 6-7 Eaton Wiring Manual 06/11 Motor-protective circuit-breakers PKZM0 and PKZM4 – current limiters CL-PKZ0 66 The current limiter module CL-PKZ0 is a short-circuit protective device specially developed for the PKZM0 and PKZM4 for non-intrinsically-safe areas. The CL module has the same base area and uses the same terminations as the PKZM0. When they are mounted on a top-hat rail alongside one another, it is possible to connect them using B3...-PKZ0 three-phase commoning links. The switching capacity of the series connected PKZM0 or PKZM4 + CL is 100 kA at 400 V. In the event of a short-circuit, the contacts of the motor-protective circuit-breaker and CL will open. While the current limiter returns for the closed rest position, the motor protective-circuit breaker trips via the instantaneous release and produces a permanent isolating gap. The system is ready to operate again, once any defect has been rectified. The current limiter can conduct an uninterrupted current of 63 A. The module may be used for individual or group protection.

These circuit-breakers protect electrical equipment from thermal overloads and in the event of a short-circuit. The NZM circuit-breakers cover the rated current range from 20 to 1600 A. 77 Depending on the version, they have additional protective functions such as residual current device, earth-fault protection or the capability for energy management by detecting load peaks, and selective load shedding. NZM circuit-breakers stand on account of their compact shape and their current-limiting characteristics. Switch-disconnectors without overload or tripping units are available in the same NZM1 NZM2 Notes The NZM7, NZM10 and NZM14 circuit-breakers are no longer contained in the Eaton range. They have been replaced by a new generation of devices. Information on the above devices is provided in this chapter. 7-2 sizes as the circuit-breakers and can be fitted with additional shunt or undervoltage release to suit the versions concerned. NZM circuit-breakers and switchdisconnectors are built and tested to the specifications in standard IEC/EN 60947. They feature isolating characteristics. In conjunction with a locking facility, they are suitable for use as main switches to IEC/EN 60204/VDE 0113, part 1. The electronic release of frame sizes NZM2, NZM3 and NZM4 feature communication capabilities. The actual states of the circuit-breakers can be visualized locally via a Data Management Interface (DMI) or converted to digital output signals. Additionally, the circuit-breakers can be connected to a network, e.g. PROFIBUS-DP. NZM3 NZM4 Circuit-breakers Overview IZMX circuit-breakers The IZMX circuit-breakers are designed for use in the high rated current range from 630 A. IZMX circuit-breakers and INX switch-disconnectors provide the main switch isolation functions required by the IEC/EN 60204-1 standard as they are lockable in the OFF position. They can therefore be used as mains switches. IZM circuit-breakers are built and tested in accordance with IEC/EN 60947. Depending on the type of equipment protected, the following main areas of application are possible with different settings to the release electronics: • System protection, • Motor protection, • Transformer protection, • Generator protection. IZMX circuit-breakers offer different electronic units from simple system protection with overload and short-circuit release right through to the digital release with graphical display and the possibility to create time selective networks. IZMX16 Eaton Wiring Manual 06/11 They can be adapted to a wide range of requirements with a comprehensive range of mounted accessories such as auxiliary contacts, trip-indicating auxiliary contacts, motor operators or voltage release, fixed-mounted or withdrawable units. With their communication capability, the IZMX circuit-breakers open up new possibilities in power distribution. Important information can be passed on, collected and evaluated, also for preventative maintenance. For example, by enabling rapid intervention in processes, system downtimes can be reduced or even prevented. Selection criteria of an IZM circuit-breaker are: • Max. short-circuit current Ikmax, • Rated operating current In, • Ambient temperature, • 3 or 4-pole design, • Fixed mounting or withdrawable units, • Protective function, • Min. short-circuit current. Detailed information on the circuit-breakers is provided in chapter 18 of the Eaton Industrial Switchgear Catalog 2010.

When de-energized, the system is in the rest position. A normally open contact actuates the system. If the shunt release is rated for intermittent duty (overexcited shunt release with 5 % DF), the intermittent operation must be ensured by connecting an appropriate auxiliary contact of the circuit-breaker upstream. This measure is not required when using a shunt release with 100 % DF. Shunt releases are used for remote tripping when an interruption in the voltage is not intended to lead to automatic disconnection. Tripping does not occur in the event of wire breakage, loose contacts or undervoltage.

Undervoltage releases are also suitable for very reliable interlocking and remote off switching since disconnection always occurs in the event of a fault (e.g. wire breakage in the control circuit). The circuit-breakers cannot be reclosed when the undervoltage releases are de-energized. The system is in the rest position when energized. Actuation is produced by a normally closed contact. Undervoltage releases are always designed for uninterrupted operation. These are the ideal tripping elements for totally reliable interlocking tasks (e.g. emergency offswitching ). Off-delayed undervoltage release UV L1 (L+) Q1 D1 D2 U< E1 -Q1 -S11 0 -Q1 D1 U< The off-delayed undervoltage release (Q1) is a combination of a separate delay unit (UVU) and the respective release.

Because they close early, they can be used for interlocks with other switches. Furthermore, they allow a switch position indication. With the circuit-breaker in the Tripped position, the HIV is in the same position as it is at OFF. Because of its early-make characteristics, it can be used to apply voltage to the undervoltage release. → Section ”Undervoltage releases”, page 7-5, → Section ”Remote switch-off with voltage release”, page 7-11, → Section ”Applications of the undervoltage release”, page 7-13. 77 HIV + I + L1L2L3 HIV NZM4 + L1L2L3 I HIV + L1L2L3 0→I Switch on 0←I Switch off +← I Trip ■ Contact closed □ Contact open I HIV + L1L2L3 + I HIV 7-7 Eaton Wiring Manual 06/11 Circuit-breakers Internal circuit diagrams NZM Maximum configuration NZM... 1 2 3 4 HIN: 1 NO, 1 NC, 2 NO, 2 NC or 1NO/1NC 1 2 3 3 HIA: 1 NO, 1 NC, 2 NO, 2 NC or 1NO/1NC 1 1 1 2 HIV: 2 S 1 1 1 1 If a motor operator is used at the same time, a configuration with 2 NO, 2 NC or 1 NO/1NC (double auxiliary contact) is restricted on the NZM3 circuit-breaker.

For this only the operating voltage, the motor rating, the various short-circuit ratings and coordination types are required. The selector slide can be used for dimensioning devices with short-circuit coordination types 1 and 2. Standard cable cross-sections and permissible cable lengths are stated for the tripping of protective devices in compliance with standards. They can vary according to the installation requirements. The selector slide has several variants of the movable section with numerical values for DOL and reversing starters or star-delta starters. The selector slide can be obtained free of charge. If you prefer to use the selection aid online, this is available at: www.eaton.com/moeller/support (Online Selection Tools) 88 8-3 All about Motors Motor protection Overload relay with reclosing lockout They should always be used where continuous contact devices (two-wire control) are concerned (e.g. pressure and position switches), to prevent automatic restarting. The reset button can be fitted as an external feature in order to make it accessible to all personnel. Overload relays for example are always supplied with manual reset. but can be converted to automatic reset by the user. Overload relays without reclosing lockout 88 They can be used only with pulsed contact devices (three-wire control) such as pushbuttons etc., because on these, the cooling of the bimetal strips cannot lead to automatic reconnection. Special circuitry Special circuitry such as is found in star-delta switches, individually compensated motors, current transformer-operated overload relays etc. may require that the relay settings deviates from the motor rated operational current. Frequently recurring operating cycles It makes motor protection difficult. The relay should be set to higher than rated motor current in view of its shorter time constant. Motors which are rated for a high operating frequency will stand this setting to a certain degree. Although this will not ensure complete protection against overload, it will nevertheless provide adequate protection against non-starting. 8-4 Eaton Wiring Manual 06/11 Back-up fuses and instantaneous releases They are needed to protect not only the motor, but also the relay, against the effects of short-circuits. Their maximum rating is shown clearly on every relay and must be adhered to without fail. Higher ratings – chosen for instance according to the cable cross-section – would lead to the destruction of the motor and relay. The following important questions and answers give a further guide to the behaviour of an installation with motor protection. To what current must the overload relay properly be set? To the rated motor current – no higher, no lower. A relay set to too low a figure will prevent the full utilization of the motor; set too high, it will not guarantee full overload protection. If a correctly set relay trips too frequently, then either the load on the motor should be reduced or the motor should be exchanged for a larger one. When is it right for the overload relay to trip? Only when the current consumption of the motor increases due to mechanical overloading of the motor, undervoltage or phase failure when the motor is under full load or thereabout, or when the motor fails to start due to a stalled rotor. All about Motors Motor protection When does the overload relay fail to trip in good time although the motor is endangered? With changes in the motor which do not cause an increase in current consumption: Effects of humidity, reduced cooling due to a reduction in speed or motor dirt, temporary additional external heating of the motor or bearing wear. Eaton Wiring Manual 06/11 3-pole overload relays should be so connected in the case of single-phase and DC motors so that all three poles of the overload relay carry the current, whether in 1-pole or 2-pole circuits. 1 pole 2 pole What causes destruction of the overload relay? Destruction will take place only in the event of a short-circuit on the load side of the relay when the back-up fuse is rated too high. In most cases, this will also endanger the contactor and motor. Therefore, always adhere to the maximum fuse rating specified on every relay. An important characteristic feature of overload relays conforming to IEC/EN 60947-4-1 are the tripping classes (CLASS 10 A, 10, 20, 30). They determine different tripping characteristics for the various starting conditions of motors (normal starting to heavy starting duty). 8-5 88 Eaton Wiring Manual 06/11 All about Motors Motor protection Pick-up times Response limits of time-delayed overload relays at all-pole load.

Overload capacity Overload relays and releases have heating coils which can be thermally destroyed by overheating. The making and breaking currents of the motor flow in thermal overload relays which are used for motor protection. These currents are between 6 and 12 x Ie (rated operational current), depending on the utilization category and the size of the motor. The point of destruction depends on the frame size and design. It is usually approximately 12 to 20 x Ie. 88 The point of destruction is the point of intersection between the projected tripping characteristic curves and the multiple of the current. Short-circuit strength of the main circuit With currents that exceed the breaking capacity of the motor starter in relation to the utilization category (EN 60947-1, VDE 0660, Section 102, Table 7), it is permissible for the current flowing during the break time of the protective device to damage the motor starter. The permissible behaviour of starters under short-circuit conditions is defined in the so-called types of coordination (1 and 2). It is common practice to state in 8-7 All about Motors Motor protection the details of protective devices which type of coordination is ensured by them. Type 1 coordination In the event of a short circuit the starter must not endanger persons and installations. It does not have to be fit for renewed operation without repair. Type 2 coordination In the event of a short-circuit the starter must not endanger persons and installations. It must be fit for renewed operation. There is a risk of contact weld. for which the manufacturer must give maintenance instructions. Eaton Wiring Manual 06/11 The tripping type of the overload relay must not differ from the given tripping characteristic after a short-circuit. Short-circuit strength of the auxiliary contact The manufacturer details the required overcurrent protective device. The combination is subjected to three test disconnection's at 1000 A prospective current with a power factor between 0.5 and 0.7 at rated operational voltage. Welding of the contacts may not occur (EN 60947-5-1, VDE 0660 Part 200). Motor protection in special applications 88 Heavy starting duty An adequate tripping time is essential in order to allow a motor to start up smoothly. In the majority of cases, overload relays such as motor-protective circuit-breakers PKZ(M) or circuit-breakers NZM can be used. The tripping time can be taken from the tripping characteristics in the main catalogue, Industrial Switchgear. In the case of especially high-inertia motors, whose run-up time exceeds the tripping delay of the above devices, it would be completely wrong to adjust an overload relay which tripped out before the run-up time expired, to a current level higher than the rated motor current. This would, it is true, solve the starting problem, but the motor would no longer be adequately protected during run. However, there are other solutions to the problem: 8-8 Current transformer-operated overload relays ZW7 The ZW7 consists of three special saturable core current transformers, supplying an overload relay Z… It is used principally for medium and large motors. Up to two times rated operational current Ie, the transformation ratio I1/I2 of the saturable core current transformers is practically linear. Within this range it does not differ from the normal overload relay, i.e. it provides normal overload protection during normal operation. However, within the transformer characteristic range (I > 2 x Ie) , the secondary current no longer increases proportionally to the primary current. This non-linear increase in the secondary current produces an extended tripping delay if overcurrents greater than twice rated operational current occur, and hence permits longer start-up times. All about Motors Motor protection Adjusting the current transformer-operated overload relay ZW7 for lower rated motor current The setting ranges quoted in the main catalogue, Industrial Switchgear, apply when the incoming cable is looped once through the transformer relay. If the current transformer-operated overload relay ZW7 is required to provide protection to a motor of below 42 A rating (minimum value in the setting range of 42 A to 63 A), the necessary range adjustment is achieved by looping the incomer several times through the aperture in the relay. The change in the rated motor current quoted on the rating plate is inversely proportional to the number of loops. Example: With the ZW7-63 relay, which has a setting range from 42 A to 63 A, a rated motor current of 21 A to 31.5 A can be accommodated by looping the leads twice through the relay. Eaton Wiring Manual 06/11 The motor is a limiting factor with regard to the tripping delay of the current transformer-operated relay and the bridging period. One must ensure that the motor is able to tolerate the high temperature generated by direct starting, for the prescribed starting time. Motor and starting procedure have to be selected carefully when dealing with machines having a very large rotating mass, which are practically the only ones subject to this problem when direct starting is used. Depending on the operating conditions adequate protection of the motor winding may no longer be given by an overload relay. In that case it must be weighed up whether an electronic overload relay ZEV, ZEB or a thermistor overload relay EMT 6 in conjunction with an overload relay Z meets the requirements. Example circuits → page 8-10 Bridging of motor protection during starting For small motors the bridging of the motor protection during starting is more economical. Because of the additional parallel contactor, the overload relay does not carry the full current during starting. Only when the motor has reached full speed is the bridging contactor switched off and the full motor current is then carried by the overload relay. Provided it has been set correctly to the rated motor current, this will ensure full motor protection during operation. Starting must be monitored. 8-9 88 Eaton Wiring Manual 06/11 All about Motors Motor protection Star-delta switch (Δ) 1 operating direction Changeover time with overload relay in position A: < 15 s B: > 15 < 40 s Ie B -Q15 -Q11 -Q13 -Q11 A C: > 40 s Ie Ie -Q15 -Q13 -Q11 -Q15 C -Q13 Setting of the overload relay 0.58 x Ie 1 x Ie 0.58 x Ie Full motor protection in Only partial motor protection Motor not protected in 8 (star) position in 8 position 8 position 88 Multi-speed switches One tapped winding 2 speeds 2 separate windings -Q17 -Q21 -Q23 -Q17 -Q21 3 speeds 1 x tapped winding + 1 winding -Q23 -Q17 -Q11 Attention must be paid to short-circuit protective device of the overload relays.

All about Motors Motor protection Eaton Wiring Manual 06/11 Thermistor overload relay for machine protection Thermistor overload relays for machine protection are used in conjunction with temperature-dependent semi-conductor resistors (thermistors) for monitoring the temperature of motors, transformers, heaters, gases, oils, bearings etc. Depending on the application, thermistors have positive (PTC thermistors) or negative (NTC thermistors) temperature coefficients. With PTC thermistors the resistance at low temperature is small. From a certain temperature it rises steeply. On the other hand, NTC thermistors have a falling resistance-temperature characteristic, which does not exhibit the pronounced change behaviour of the PTC thermistor characteristic. Temperature monitoring of electric motors Thermistor overload relays for machine protection EMT6 comply with the characteristics for the combination of protective devices and PTC sensors to EN 60947-8. They are therefore suitable for monitoring the temperature of series motors. When designing motor protection, it is necessary to differentiate between stator-critical and rotor-critical motors: • Stator-critical Motors whose stator winding reaches the permissible temperature limit quicker than the rotor. The PTC sensor fitted in the stator winding ensures that the stator winding and rotor are adequately protected even with a stalled rotor. • Rotor-critical Squirrel-cage motors whose rotor in the event of stalling reaches the permissible temperature limit earlier than the stator winding. The delayed temperature rise in the stator can lead to a delayed tripping of the thermistor overload relay for machine protection. It is therefore advisable to supplement the protection of rotor-critical motors by a conventional overload relay. Three-phase motors above 15 kW are usually rotor-critical. Overload protection for motors in accordance with IEC 204 and IEC/EN 60204. These standards specify that motors above 2 kW used for frequent starting and stopping should be adequately protected for this type of duty. This can be achieved by fitting temperature sensors. If the temperature sensor is not able to ensure adequate protection with stalled rotors, an overcurrent relay must also be provided. Generally, where there is frequent starting and stopping of motors, intermittent operation and excessive frequency of operation, the use of overload relays in conjunction with thermistor overload relays is to be recommended. In order to avoid premature tripping out of the overload relay in these operating conditions, it is set higher than the predefined operating current. The overload relay then assumes stalling protection; the thermistor protection monitors the motor winding. 8-13 88 Eaton Wiring Manual 06/11 All about Motors Motor protection Thermistor overload relays for machine protection can be used in conjunction with up to six PTC sensors to DIN 44081 for direct monitoring of temperatures in Ex e motors compliant with the ATEX directive (94/9 EC).

A reduced voltage Ua (approximately 70 % of the rated operating voltage) is supplied to the motor when starting via the starting transformer. Thus, the current taken from the mains is reduced to approximately half the direct inrush current. Three-phase automatic rotor starters with starting resistors Resistors are connected in the rotor circuit of the motor to reduce the inrush current of motors with slipring rotors. The current taken from the mains is thus reduced. In contrast to stator resistance starters, the torque of the motor is practically proportional to the current taken from the mains. The number of steps of the automatic starter is determined by the maximum permissible inrush current and by the type of the motor. 8-15 88 Eaton Wiring Manual 06/11 All about Motors Notes on engineering Important data and features of three-phase automatic starters 1) Type of starter Stator resistance starter (for squirrel-cage motors) Rotor starter (for slipring rotors) 2) Part no. of starter Star-delta switches With starting resistors With start-up transformers Rotor resistance starter 3) Number of starting stages 1 only Normally 1 Normally 1 Selectable (no longer selectable when current or torque have been determined) 4) Voltage reduction at the motor 0.58 x rated operational voltage Selectable: a x rated operational voltage (a < 1) e.g. 0.58 as with 8△-switch Selectable: 0.6/0.7/0.75 x Ua (transformer tappings) None 5) Inrush current taken from mains 0.33 x inrush current at rated operational voltage a x inrush current at rated operational voltage Selectable (see 4) 0.36/0.49/0.56 x inrush current at rated operational voltage Selectable: from 0.5 to about 2.5 x rated operational current 88 Selectable (see 4) 0.6/0.7/0.75 x Ie 5a) Inrush current at the motor 6) Starting torque 0.33 x tightening torque at rated operational voltage a2 x tightening torque at rated operational voltage Selectable (see 4) 0.36/0.49/0.56 x tightening torque at rated operational voltage Selectable (see 5) from 0.5 to pull-out torque 7) Current and torque reduction Proportional Currentreduction less than torque reduction Proportional Current reduction much greater than torque reduction.

A discharge circuit or discharge device must reduce the residual voltage of the capacitor to less than 50 V within a minute of the capacitor being switched off. When installing capacitors, the VDE specification 0560 part 4 (Germany) and the standards which apply to each country should be observed. According to these, capacitors not directly connected to an electrical device which forms a discharge circuit, should be equipped with a rigidly connected discharge device. Capacitors connected in parallel to the motor do not require a discharge device, since discharging is performed via the motor winding.

This produces inrush current peaks which can exceed 150 times the rated operational current. A further reason for these peak currents is the use of low-loss capacitors as well as the compact construction, with short connecting elements between contactor and capacitor. Where standard contactors are used, there is danger of welding. Special contactors for capacitors such as those available from Eaton in the DILK… range which can control inrush current peaks of up to 180 times the rated current, should be used here. If no special contactors are available, the inrush currents can be damped by additional inductance's. This is achieved either by longer input wirings to the 8-18 capacitors or by inserting an air-cored coil with a minimum induction of approximately 6 μH (5 windings, diameter of the coil approximately 14 cm) between contactor and capacitor. The use of series resistors is another way of reducing high inrush currents. Use of reactors Frequently the capacitors in group compensation are provided with reactors to avoid harmonics. The reactors also act to limit the inrush current and normal contactor can be used.

With contactor combinations which are made up of several basic types, the basic type is always maintained. Thus, the circuit diagram for a reversing star-delta starter, for example, is formed by combining the basic circuit of the reversing contactor and that of the standard star-delta starter.

At the same time, voltage is applied to the timing relay K1. The mains contactor Q11 is closed by Q14/44-43 and maintains itself via Q11/14-13. When the set time – which corresponds to the start-up time of the motor - has elapsed, the bridging contactor Q14 is disconnected by K1/16-15. K1 is likewise disconnected and, exactly as Q14, can only be energized again after the motor has been switched off by pressing pushbutton 0. The N/C Q11/22-21 prevents Q14 and K1 closing whilst the motor is running. In the event of an overload, normally closed contact 95-96 on the overload relay F2 effects de-energization. 8-29 Eaton Wiring Manual 06/11 All about Motors Direct-on-line start of three-phase motors 2 operating directions, DIUL reversing contactor Fuses with overload relays Short-circuit protection1) for contactor and overload relay by means of fuses F1.

It switches on the motor running clockwise and maintains itself after button I is enables via its own auxiliary contact Q11/14-13 and pushbutton 0 (three-wire control). The normally closed contact Q11/22-21 electrically inhibits the closing of contactor Q12. When pushbutton II is pressed, contactor Q12 closes (motor running anticlockwise). Depending on the circuit, direction can be changed from clockwise to anticlockwise either after pressing pushbutton 0, or by directly pressing the pushbutton for the reverse direction. In the event of an overload, normally closed contact 95-96 of the overload relay F2 or the normally open contact 13-14 of the motor-protective circuit-breaker or the circuit-breaker will switch.

Pushbutton I switches on the feed motion via Q17. Q17 maintains itself via its N/O 13-14. If the feed movement is to occur at high-speed star contactor Q23 is energized via pushbutton II which energizes the high speed contactor Q21 via its N/O Q23/13-14. Both of the contactors are maintained via Q21/13-14. A direct switch over from feed to high-speed during the process is possible.

The overload relay can also be operated in a star circuit as it is usually connected in series with the motor winding and the relay current flowing through it = rated motor current x 0.58. The complete circuit diagram → Section ”Automatic star-delta switches SDAINL”, page 8-37. Arrangement in the mains supply line Instead of the arrangement in the motor line, the overload relay can be placed in the mains supply line. The section shown here indicates how the circuit diagram differs from that on → Section ”Automatic star-delta switches SDAINL”, page 8-37. For drives where the F2 relay trips out when the motor is starting in the star connection, the F2 relay rated for the rated motor current can be switched in the mains line. The tripping delay is thus increased by approximately four to six times. In the star connection, the current also flows through the relay but here the relay does not offer full protection since its limit current is increased to 1.73 times the phase current. It does, however, offer protection against non-starting. 8-35 88 Eaton Wiring Manual 06/11 All about Motors Star-delta switching of three-phase motors -Q15 -F2 5 1 3 2 4 6 2 4 6 V2 W2 U2 88 8-36 -Q13 97 95 98 96 1 3 5 2 4 6 Configuration in the delta connection Instead of the arrangement in the motor line or mains supply line, the overload relay can be placed in the delta connection. The cutout shown here indicates the modified circuit diagram from → Section ”Automatic star-delta switches SDAINL”, page 8-37. When heavy, long-starting procedures are involved (e.g. for centrifuges) the F0.58 relay, rated for relay current = rated motor current x 2, can also be connected in the connecting cables between the delta contactor Q15 and the star contactor Q13. In the star connection no current then flows through the F2 relay. The motor is therefore not protected when starting. This connection is always used when exceptionally heavy and long starting procedures are involved and when saturable core current transformeroperated relays react too quickly.

All multi-speed switches can be used for both types of connection. The various tapped winding configurations give differential output ratios for the two speeds. Type of connection△/8 8 8/8 8 Output ratio 1/1.5–1.8 0.3/1 2 speeds – separate windings The △/ -connection comes nearest to satisfying the most usual requirement for constant torque. It has the additional advantage that, because nine terminals are available, y/d starting can be used to provide smooth starting or to reduce the starting current for the low speed condition (→ Section ”Motor windings”, page 8-50). In theory, motors with separate windings allow any combination of speed and any output ratio. Both windings are arranged in y connection and are completely independent of one another.

Multi-speed contactor switches can achieve these connecting by interlocking with suitable control circuit devices. Certain operating sequences for pole-changing motors may be necessary, or undesirable, depending on the nature of the drive. If, for example, the starting temperature rise is to be reduced or high inertia loads are to be accelerated, it is advisable to switch to low speed first and then to high speed. Fuse protection of the overload relays When a common fuse is used in the input wiring, it must not be larger than the back-up fuses specified on the nameplate of either overload relay, otherwise each relay must be protected by its own back-up fuse, as shown in the diagram. It may be necessary to prevent switching from high to low speed in order to avoid oversynchronous braking. In other cases, it should be possible to switch each speed on and off directly.

Approval of electrical equipment is based on the conformity and certification of components and assemblies to regional and country specific product and installation standards that are geared towards the proper application of these products in those markets. 9 • Product testing conducted by nationally recognized certification agencies is often required, and product certification is also subject to periodic review and auditing by the certification agency. • In the majority of cases, product certification is tied to the display of respective certification marks on the product themselves. • Product certification ratings may differ from IEC based technical data and ratings. • Product certifications are sometimes subject to additional and specific conditions of acceptability. • Design flexibility on the part of manufacturers can sometimes be impacted by the possible need to re-certify each subsequent product modification. 9-2 In addition to product certifications, a firm understanding of the standards and market conventions involved is necessary to insure that electrical components and assemblies are also properly applied. A checklist is a useful tool to clarify important issues and minimize costs during the engineering phase. Special requirements that are overlooked during the initial stages, and need to be remedied after the fact, will not only be costly but very time consuming as well. Eaton Wiring Manual 06/11 Export to World Markets and North America Approvals and certifications Special characteristics for the export to North America (USA, Canada) Technologies that have proven themselves reliable the world over are not guaranteed automatic acceptance in North America. Exports to North America must take into consideration the following: • North American certification of electrical equipment, • North American product, application, and installation standards, • Particular and specialized market conventions, • Approval of electrical installations by local inspectors (AHJ = Authority Having Jurisdiction). Particular aspects of the North American market, which are not readily known in the IEC world: • Product groupings and fields of application • Product specific differences and ratings based on certification • Differentiation of power circuits (Feeder and Branch Circuits) • Equipment limitations based on particular supply network configurations • Application related differences affecting product selection 9 9-3 Eaton Wiring Manual 06/11 Export to World Markets and North America Approvals and certifications Electrical equipment groupings in North America There is a differentiation made in North America between products used in Energy Distribution, such as molded case circuit breakers certified per the UL 489 product standard, and those found in Industrial Control, typically falling under UL 508. Product standards such as UL 489 and CSA C22.2 No. 5-09 require significantly larger air and creepage clearances in component construction than do the IEC standards and their harmonized European counterparts (EN norms). An example of its impact on component construction would be the European motor protective switch which, in North America, needs to be equipped with a large spacings terminal on its supply side whenever it is applied as a stand-alone protective device in individual motor branch circuits. 9 Electrical components used in energy distribution • Molded Case Circuit Breakers UL 489, CSA C22.2 No. 5-09 • Molded Case Switches UL 489, CSA C22.2 No. 5-09 • Enclosed Switches UL 98, CSA C 22.2 No. 4 • Fusible Disconnect Switches UL 98, CSA C 22.2 No. 4 • Fuses UL 248, CSA C22.2 No. 248 9-4 Industrial Control Equipment UL 508 and CSA C22.2 No. 14 • • • • • • Contactors Control Relays Overload Relays Cam Switches Pilot devices and Limit switches Solid State relays and equipment Programmable Controllers Eaton Wiring Manual 06/11 Export to World Markets and North America Approvals and certifications Criteria for equipment selection particular to North American conventions • Knowing the type of load and circuit is especially important in selecting the right equipment for the application. Motor starters are used exclusively for the protection and switching of motor loads. • Motor starters mounted on busbar adapters that are supplied from a feeder must have the larger electrical clearances on their incoming supply side.1) • Motor starters mounted on busbar adapters within a branch circuit are permitted to have industrial control electrical clearances on their field terminations.1) • Supplementary handles are necessary for supply circuit disconnect switches equipped with door mounted rotary handles in applications such as industrial machinery. 1) Circuit examples: Refer to diagrams on page 9-35. 9 Comprehensive information and tips on exporting electrical equipment and controls to North America can be downloaded free of charge from the Internet. www.eaton.com/moeller (News/Press, Publications) 9-5 Eaton Wiring Manual 06/11 Export to World Markets and North America Fuse classifications in North America Additional comments on Table → page 9-8 Suitable for use in: 9 UL/CSA Standards Characte ristics SCCR Typical ranges in Amps 10 kA, 250 V AC 0…600 USA Canada Class H, "Code" Class H, No. 59 "Code" UL 248-6/7, C22.2 248-6/7 FastActing Class CC Class CC UL 248-4, C22.2 248-4 FastActing Time Delay 200 kA, 600 V AC 0.5…30 Class G Class G UL 248-5, C22.2 248-5 FastActing Time Delay 100 kA, 480 V AC 21…60 100 kA, 600 V AC 0.5…20 10 kA, 600 V AC Class J Class J HRCI-J UL 248-8, C22.2 248-8 FastActing Time Delay 200 kA, 600 V AC 1…600 Class K K1, K5 Class K K1, K5 UL 248-9, C22.2 248-9 FastActing Time Delay 50 kA/100 kA/ 200 kA, 600 V AC 0…600 Class L Class L UL 248-10, C22.2 248-10 FastActing Time Delay 200 kA, 600 V AC 601…6000 Class R RK1, RK5 Class R HRCI-R RK1, RK5 UL 248-12, C22.2 248-12 FastActing Time Delay 50 kA/100 kA/ 200 kA, 600 V AC 0…600 Class T Class T UL 248-15, C22.2 248-15 FastActing 200 kA, 300 V AC 200 kA, 600 V AC 0…1200 9-6 Eaton Wiring Manual 06/11 Export to World Markets and North America Fuse classifications in North America Applications Comments Residential, Commercial, Industrial Class H, K and No. 59 "Code" fuses are physically interchangeable and fit in the same fuseholders.

Some components, like e.g. circuit-breakers, meet all relevant international standards in their base model versions and can be universally applied, except in the USA and Canada. A special line of circuit breakers, certified to UL and CSA standards, is available for export to North America. An up-to-date listing of all component certifications and classifications can be accessed via the Internet: www.moeller.net/ eaton-approbationen/en 9 In some cases, certain country specific installation and operational requirements, wiring materials and practices, as well as special circumstances such as unusual environmental conditions, must be taken into consideration. As of January 1997, all electrical equipment built in accordance with the European Low Voltage Directive and destined for sale in the European Union must bear a CE mark. 9-14 The CE mark verifies that the marked component meets all the provisions of the relevant standards and requirements pertaining to that product. The marking obligation thus enables components to gain unfettered access to the European market place. Because CE marked components are constructed in accordance with harmonized standards, certification in individual countries within the European Union is no longer necessary. An exception would be components that could also be installed in non-industrial environments. Accordingly, components such as miniature circuit breakers and residual current protective devices are often expected to bear national certification marks. The following table provides a selection of the most commonly encountered certification marks from international testing authorities.

The IP ratings shown represent a rough comparison only. A precise conversion is not possible since tests and evaluation criteria in the relevant standards differ greatly from one another. UL/CSA and NEMA type ratings are often used interchangeably. The significant difference between the two is that a UL/CSA type rating represents third party certification by an approved testing agency, which is the preferred manner in which ratings are verified in North America. North American environmental type ratings are referenced in the following standards: • • • • • NFPA 70 (National Electrical Code), CEC (Canadian Electrical Code), UL 50E, UL 508A, CSA-C22.2 No. 94-M91 (2006), NEMA 250-2008 (National Electrical Manufacturers Association).

Unlike the method of marking up to now, the function of the electrical equipment in the respective circuit primarly determines the cose letter. This means that there is some freedom in the selection of the code letters. Eaton Wiring Manual 06/11 The marking appears in a suitable position as close as possible to the circuit symbol. The marking forms the link between the equipment in the installation and the various circuit documents (wiring diagrams, parts lists, circuit diagrams, instructions). For simpler maintenance, the complete marking or part of it, can be affixed on or near to the equipment. Example of a resistor • Normal current limiter: R • Heater resistor: E • Measurement resistor: B In addition to that, Eaton specific decisions have been made with regard to the interpretation of the standard that sometimes deviate from the standard. 10 10 • The marking of connection terminals are not readable from the right. • A second code letter for the marking of the use of the equipment is not given, e.g.: timing relay K1T becomes K1. • Circuit-breakers with the main function of protection are still marked with Q. They are numbered from 1 to 10 from the top left. • Contactors are newly marked with Q and numbered from 11 to nn. e.g.: K91M becomes Q21. • Contactor relays remain K and are numbered from 1 to n. 10-2 Selected equipment with a comparison of the Eaton used code letters old – new → Table, page 10-3 Standards, formulae, tables Marking of electrical equipment Eaton Wiring Manual 06/11 Code letter Purpose Examples for electrical equipment A (several purposes) (without main purpose) B Signal generation Pressure switches; limit switches C Storage Capacitors D (reserved for later) E Energy supply Heating resistor, lamps F Protection Bimetal releases, fuses G Power supply Generator, UPS H (reserved for later) I (must not be used) J (reserved for later) KP Signal processing L (reserved for later) M Drive energy N (reserved for later) O (must not be used) P Information display Signalling and measuring devices Q Switching energy / signal flow Soft starter, contactor, motor starter R Energy flow limitation Reactor coils, diodes S Manual signal generation Control circuit devices T Energy conversion Frequency inverters, transformer U Object fixing V Material processing W Power transmission X Object connection Y, Z (reserved for later) Contactor relay, timing relays Motor Electro filter Terminal, plug connector 10-3 10 10 Standards, formulae, tables Protective measures Eaton Wiring Manual 06/11 Protection against electrical shock to IEC 60364-4-41/DIN VDE 0100-410 This is divided into basic protection (previously protection against direct contact), fault protection (previously protection against indirect contact) and protection against both direct and indirect contact. 10 10 • Basic protection These are all the measures for the protection of personnel and working animals from dangers which may arise from contact with live parts of electrical equipment. • Fault protection This is the protection of personnel and working animals from fault scenarios which may arise from accidental contact with components or extraneous conductive parts. • Additional protection If basic or fault protection fails or there is a greater potential danger, residual current protective devices with IΔn ≦ 30 mA offer additional protection. Protection must be ensured by either a) the equipment itself or b) the use of protective measures when erecting the installation or c) a combination of a) and b). 10-4 If basic, fault and additional protection is combined in a suitable manner the following protective measures result and are covered in section 410 of DIN VDE 0100: • Automatic disconnection of the power supply (0100-411) • Double or reinforced insulation (0100-412) • Protective separation (0100-413) • Safety extra low voltage SELV or PELV (0100-414) One of the key amendments to DIN VDE 0100-410 of June 2007 was the additional protection for final circuits for outdoor areas and sockets (411.3.3). This stipulates that an additional protection must be provided by means of residual current devices (RCDs) with IΔn ≦ 30 mA for sockets ≦ 20 A, as well as final current circuits for portable equipment ≦ 32 A used outdoors. The previous recommendation has therefore been changed to a mandatory requirement in order to increase safety.

(in depth explanations on new DIN VDE 0100-430 contained in volume 143, 3rd edition, of the VDE publication series).

Remark: For the protection of conductors against overload the following conditions must be fulfilled (source: DIN VDE 0100-430) For adjustable protective devices, In corresponds to the value set.

Eaton Wiring Manual 06/11 Standards, formulae, tables Overcurrent protection of cables and conductors Note: Reasons for the current carrying capacity being reduced: Reduction of the conductor cross-section, a different installation method, different conductor insulation, a different number of conductors. Protective devices for overload protection should not be fitted if interruption of the circuit could prove hazardous. The circuits must be laid out in such a way that no possibility of overload currents occurring need be considered. Examples: Timing relay = function relay with contacts and coils Time switch = function relay with contacts • Energizing circuits for rotating machines • Feeder circuits of solenoids • Secondary circuits of current transformers • Circuits for safety purposes Short-circuit protection Short-circuit protection means providing protective devices which will interrupt short-circuit currents in the conductors of a circuit before they can cause a temperature rise which may damage the conductor insulation, the terminals and connections, or the area around the cables and conductors. In general, the permissible disconnection time t for short circuits of up to 5 s duration can be specified approximately using the following equation: S 2 t = ,+ k x ---31 I or I2 x t = k2 x S2 The meaning of the symbols is as follows: t: Permissible disconnection time in the event of short-circuit in s S: Conductor cross-section in mm2 I: r.m.s. value of the current with a maximum short-circuit in A k: Constants with the values – 115 for PVC-insulated copper conductors – 76 for PVC-insulated aluminum conductors – 141 for rubber-insulated copper conductors – 93 for rubber-insulated aluminum conductors – 115 for soft-solder connections in copper conductors – Other values for k are given in Table 43A of DIN VDE 0100-430. With very short permissible disconnection times (< 0.1 s) the product from the equation k2 x S2 must be greater than the I2 x t value of the current-limiting device stated by manufacturer. Arrangement of protective devices for protection in the event of a short-circuit. Protective devices for protection in the event of a short-circuit must be fitted at the start of every circuit and at every point at which the short-circuit current-carrying capacity is reduced unless a protective device fitted upstream can ensure the necessary protection in the event of a short circuit. 10-13 10 10 Eaton Wiring Manual 06/11 Standards, formulae, tables Overcurrent protection of cables and conductors Note: Reasons for the reduction in the shortcircuit current-carrying capacity can be: Reduction of the conductor cross-section, other conductor insulation. Short-circuit protection must not be provided where an interruption of the circuit could prove hazardous. In these cases two requirements must be fulfilled: • The cable must be laid so that the risk of short-circuits is reduced to a minimum. • The cable must not be laid in the vicinity of flammable materials. Protection of the main poles and the neutral conductors Protection of the main poles Overcurrent protection devices must be provided in every main pole: they must disconnect the conductor in which the overcurrent occurs, but not necessarily also disconnect the other live conductors. Note: 10 10 Where the disconnection of an individual main pole could prove hazardous, as for example, with three-phase motors, suitable precautions must be taken. Motorprotective circuit-breakers and circuitbreakers disconnect in 3 poles as standard. Protection of the neutral conductor: 1. In installations with a directly earthed neutral point (TN or TT systems) Where the cross-section of the neutral conductor is less than that of the main poles, an overcurrent monitoring device appropriate to its cross-section is to be provided in the neutral conductor; this overcurrent monitoring device must result in the disconnection of the phase conductors but not necessarily that of the neutral conductor. An overcurrent monitoring device in the neutral conductor is not necessary where: 10-14 • the neutral conductor is protected in the event of a short-circuit by the protective device for the main poles • the largest current which can flow through the neutral conductor is, in normal operation, considerably less than the current carrying capacity of this conductor. Note: This second condition is met provided that the power transferred is divided as evenly as possible among the main poles, for example where the total power consumption of the load connected between phase and neutral conductors, lamps and socket outlets is much less than the total power transferred via the circuit. Eaton Wiring Manual 06/11 Standards, formulae, tables Overcurrent protection of cables and conductors 2.In installations without a directly earthed neutral point (IT system) Where it is necessary for the neutral conductor to be included, an overcurrent monitoring device must be provided in the neutral conductor of each circuit, to cause disconnection of all live conductors in the relevant circuit (including the neutral conductor). The overcurrent monitoring device may however be omitted where the neutral conductor in question is protected against short-circuit by an upstream protective device, such as in the incoming unit of the installation. Disconnection of the neutral conductor Where disconnection of the neutral conductor is specified, the protective device used must be designed in such a way that the neutral conductor cannot under any circumstances be disconnected before the phase conductors and reconnected again after them. 4-pole NZM circuit-breakers always meet these conditions. 10 10 10-15 10 10 10-16 Number of In heat-insulating walls, in cable conduit under the surface Cable cores in cable conduit on the wall 2 3 2 3 Current-carrying capacity Iz in A for 25°C ambient air temperature and 70°C operating temperature.

Safety requirements regarding the protection of personnel, machines and material according to the European Machinery Safety Directive are highlighted under the heading “Safety of machines”. The degree of possible danger is to be estimated by risk assessment. The standard also includes requirements for equipment, engineering and construction, as well as tests to ensure faultless function and the effectiveness of protective measures. The following paragraphs are an extract from the standard. Mains isolating device (main switches) Every machine must be equipped with a manually-operated mains isolating device. It must be possible to isolate the entire electrical equipment of the machine from the mains using the mains isolating device. The breaking capacity must be sufficient to simultaneously disconnect the stalled current of the largest motor in the machine and the total current drawn by all the other loads in normal operation. Its Off position must be lockable and must not be indicated until the specified clearances and creepage distances between all contacts have been achieved. It must have only one On and one Off position with associated stops. Star-delta, reversing and multi-speed switches are not permissible for use as mains isolating devices. The tripped position of circuit-breakers is not regarded as a switch position, therefore there is no restriction on their use as mains isolating devices. Where there are several incomers, each one must have a mains isolating device. Mutual interlocking must be provided where a hazard may result from only one mains isolating device being switched off. Only circuit-breakers may be used as remotely-operated switches. They must be provided with an additional handle and be lockable in the Off position. Protection against electric shock The following measures must be taken to protect personnel against electric shock. Basic protection/protection against direct contact This is understood as meaning protection by means of an enclosure which can only be opened by qualified personnel using a key or special tool. Such personnel is not obliged to disable the mains isolating device before opening the enclosure. Live parts must be protected against direct contact in accordance with DIN EN 50274 or VDE 0660-514. Where the mains isolating device is interlocked with the door, the restrictions mentioned in the previous paragraph cease to apply because the door can only be opened when the mains isolating device is switched off. It is permissible for an 10-21 10 10 Standards, formulae, tables Electrical equipment of machines interlock to be removable by an electrician using a tool, e.g. in order to search for a fault. Where an interlock has been removed, it must still be possible to switch off the mains isolating device. Where it is possible for an enclosure to be opened without using a key and without disconnection of the mains isolating device, all live parts must at the very least comply with IP2X or IPXXB degree of Eaton Wiring Manual 06/11 protection in accordance with DIN EN 60529; VDE 0470-1. Fault protection – Protection against indirect contact This involves prevention of a dangerous touch voltage resulting from faulty insulation. To meet this requirement, protective measures in accordance with IEC 60364-4-410; VDE 0100-410 must be used. Protection of equipment Protection in the event of power failure When the power returns following a failure in the supply, machines or parts of machines must not start automatically where this would result in a dangerous situation or damage to property. With contactor controls this requirement can easily be met via self-maintaining circuits. 10 10 For circuits with two-wire control, an additional contactor relay with three-wire control in the input wiring to the actuating circuit can carry out this function. Mains isolating devices and motor-protective circuit-breakers with undervoltage releases also reliably prevent automatic restarting on return of voltage. Overcurrent protection No overcurrent protective device is normally required for the mains supply cable. Overcurrent protection is provided by the protective device at the head of the input wiring. All other circuits must be protected by means of fuses or circuitbreakers. The stipulation for fuses is that replacement must be freely obtainable in the country in which the fuses are used. 10-22 This difficulty can be avoided by using circuit-breakers, with the added benefits of all-pole disconnection, rapid operational readiness and prevention of singlephasing. Overload protection of motors Continuously operating motors above 0.5 kW must be protected against overload. Overload protection is recommended for all other motors. Motors which are frequently starting and braking are difficult to protect and often require a special protective device. Built-in thermal sensors are particularly suitable for motors with restricted cooling. In addition, the fitting of overload relays is always recommended, particularly as protection in the event of a stalled rotor. Standards, formulae, tables Electrical equipment of machines Eaton Wiring Manual 06/11 Control functions in the event of a fault A fault in the electrical equipment must not result in a dangerous situation or in damage. Suitable measures must be taken to prevent danger from arising. The expense of using appropriate measures can be extremely high if applied generally. To permit a better assessment of the magnitude of the risk in conjunction with the respective application, the standard DIN EN ISO 13849-1 has been published: “Safety-related parts of control systems Part 1: General rules for design”. The use of risk assessment to DIN EN ISO 13849-1 is dealt with in the Eaton safety manual “Safety Technology for Machines and Systems” (Order No. PU05907001Z). Emergency switching off device Every machine which could potentially cause danger must be equipped with an emergency switching off device which, in a main circuit may be an emergency switching off switch, and in a control circuit an emergency switching off control circuit device. Actuation of the Emergency-Stop device must result in all current loads which could directly result in danger, being disconnected by de-energization via another device or circuit, i.e. electromechanical devices such as contactors, contactor relays or the undervoltage release of the mains isolating device. For direct manual operation, emergency switching off control circuit devices must have a mushroom-head push-button and positively opening contacts. Once the emergency switching off control circuit device has been actuated, it must only be possible to restart the machine after local resetting. Resetting alone must not allow restarting. Furthermore, the following apply for both emergency-stop switch and emergency switching off control circuit device: • The handle must be red with a yellow background • Emergency switching off devices must be quickly and easily accessible in the event of danger • The emergency switching off function must take precedence over all other functions and operations • It must be possible to determine functional capability by means of tests, especially in severe environmental conditions. • Where there is separation into several Emergency-Stop areas, it must be clearly discernible to which area an EmergencyStop device applies Emergency operations It is not clear however from the term emergency switching off which functions are carried out with this. In order to be able to give a more precise definition here, DIN EN 60204-1 describes two specific functions: 1. Devices for emergency stop This involves the possibility of stopping hazardous motion as quickly as possible. 2. Devices for emergency switching off Where there is a risk of an electric shock by direct contact, e.g. with live parts in electrical operating areas, then an Emergency-Off device shall be provided. 10-23 10 10 Standards, formulae, tables Electrical equipment of machines Eaton Wiring Manual 06/11 Colors of pushbuttons and their meanings to DIN EN 60073; VDE 0199 DIN EN 60204-1; VDE 0113-1, Table 2 Color Meaning Typical application RED Emergency • Emergency switching off • Fire fighting YELLOW Abnormal condition Intervention, to suppress abnormal conditions or to avoid unwanted changes BLUE Enforced action Resetting function GREEN Normal Start from safe condition WHITE No specific meaning assigned • Start/ON (preferred) • Stop/OFF GREY • Start/ON • Stop/OFF BLACK • Start/ON • Stop/Off (preferred) 10 10 10-24 Standards, formulae, tables Electrical equipment of machines Eaton Wiring Manual 06/11 Colors of indicator lights and their meanings to DIN EN 60073; VDE 0199 DIN EN 60204-1; VDE 0113-1, Table 4 Color Meaning Description Typical application RED Emergency Warning of potential danger or a situation which requires immediate action • Failure of pressure in the lubricating system • Temperature outside specified (safe) limits • Essential equipment stopped by action of a protective device YELLOW Abnormal condition Impending critical condition • Temperature (or pressure) different from normal level • Overload, which is permissible for a limited time BLUE Enforced action Operator action essential • Remove obstacle • Switch over to Advance GREEN Normal Indication of safe operating conditions or authorization to proceed, clear way • Cooling liquid circulating • Automatic tank control switched on • Machine ready to be started WHITE Neutral Any meaning: may be used whenever doubt exists about the applicability of the colors RED, YELLOW or GREEN; or as confirmation • Motor running • Indication of operating modes Colors of illuminated pushbutton actuators and their meanings Both tables are valid for illuminated pushbutton actuators, Table 1 relating to the function of the actuators. 10-25 10 10 Standards, formulae, tables Electrical equipment of machines Eaton Wiring Manual 06/11 Safety-related characteristic values to EN ISO 13849-1 and IEC 62061 A safety-related system can consist of one or several components.

The rated motor currents are for standard 1500 r.p.m. three-phase motors with normal inner and outer surface cooling. D.O.L. starting: 8/Δ starting: Maximum starting current: 6 x rated motor current, maximum starting time: 5 sec. Maximum starting current: 2 x rated motor current, maximum starting time: 15 sec. Motor overload relay in phase current: set to 0.58 x rated motor current. Rated fuse currents for 8/Δ starting also apply to three-phase motors with slip-ring rotors. For higher rated currents, starting currents and/or longer starting times, larger fuses will be required. This table applies to “slow” or “gL” fuses (VDE 0636). In the case of NH fuses with aM characteristics, fuses are to be selected according to their rated operational current. 10 10 10-43 Eaton Wiring Manual 06/11 Standards, formulae, tables Rated motor currents Motor power 230 V Rated motor current 10 10 Direct starting 8/Δ A A Rated motor current Fuse Direct starting A A 8/Δ kW cos ϕ η [%] 0.06 0.09 0.12 0.18 0.7 0.7 0.7 0.7 58 60 60 62 0.37 0.54 0.72 1.04 2 2 4 4 – – 2 2 0.21 0.31 0.41 0.6 2 2 2 2 – – – – 0.25 0.37 0.55 0.75 0.7 0.72 0.75 0.79 62 66 69 74 1.4 2 2.7 3.2 4 6 10 10 2 4 4 4 0.8 1.1 1.5 1.9 4 4 4 6 2 2 2 4 1.1 1.5 2.2 3 0.81 0.81 0.81 0.82 74 74 78 80 4.6 6.3 8.7 11.5 10 16 20 25 6 10 10 16 2.6 3.6 5 6.6 6 6 10 16 4 4 6 10 4 5.5 7.5 11 0.82 0.82 0.82 0.84 83 86 87 87 14.8 19.6 26.4 38 32 32 50 80 16 25 32 40 8.5 11.3 15.2 21.7 20 25 32 40 10 16 16 25 15 18.5 22 30 0.84 0.84 0.84 0.85 88 88 92 92 51 63 71 96 100 125 125 200 63 80 80 100 29.3 36 41 55 63 63 80 100 32 40 50 63 37 45 55 75 0.86 0.86 0.86 0.86 92 93 93 94 117 141 173 233 200 250 250 315 125 160 200 250 68 81 99 134 125 160 200 200 80 100 125 160 90 110 132 160 0.86 0.86 0.87 0.87 94 94 95 95 279 342 401 486 400 500 630 630 315 400 500 630 161 196 231 279 250 315 400 400 200 200 250 315 200 250 315 400 0.87 0.87 0.87 0.88 95 95 96 96 607 – – – 800 – – – 630 – – – 349 437 544 683 500 630 800 1000 400 500 630 800 450 500 560 630 0.88 0.88 0.88 0.88 96 97 97 97 – – – – – – – – – – – – 769 – – – 1000 – – – 800 – – – 10-44 A 400 V Fuse A Eaton Wiring Manual 06/11 Standards, formulae, tables Rated motor currents 440 V Rated motor current A 500 V Fuse Direct starting A 8/Δ A Rated motor current A 690 V Fuse Direct starting A 8/Δ A Rated motor current A Fuse Direct starting 8/Δ A A 0.19 0.28 0.37 0.54 2 2 2 2 – – – – 0.17 0.25 0.33 0.48 2 2 2 2 – – – – 0.12 0.18 0.24 0.35 2 2 2 2 – – – – 0.76 1 1.4 1.7 2 4 4 4 – 2 2 2 0.7 0.9 1.2 1.5 2 2 4 4 – 2 2 2 0.5 0.7 0.9 1.1 2 2 4 4 – – 2 2 2.4 3.3 4.6 6 4 6 10 16 2 4 6 10 2.1 2.9 4 5.3 6 6 10 16 4 4 4 6 1.5 2.1 2.9 3.8 4 6 10 10 2 4 4 4 7.7 10.2 13.8 19.8 16 20 25 32 10 10 16 25 6.8 9 12.1 17.4 16 20 25 32 10 16 16 20 4.9 6.5 8.8 12.6 16 16 20 25 6 10 10 16 26.6 32.8 37 50 50 63 80 100 32 32 40 63 23.4 28.9 33 44 50 50 63 80 25 32 32 50 17 20.9 23.8 32 32 32 50 63 20 25 25 32 61 74 90 122 125 125 125 160 80 100 100 125 54 65 79 107 100 125 160 200 63 80 80 125 39 47 58 78 80 80 100 160 50 63 63 100 146 179 210 254 200 250 250 315 160 200 250 250 129 157 184 224 200 250 250 315 160 160 200 250 93 114 134 162 160 200 250 250 100 125 160 200 318 397 495 621 400 630 630 800 315 400 630 800 279 349 436 547 400 500 630 800 315 400 500 630 202 253 316 396 315 400 500 630 250 315 400 400 699 – – – 800 – – – 800 – – – 615 – – – 800 – – – 630 – – – 446 491 550 618 630 630 800 800 630 630 630 630 10 10 10-45 Eaton Wiring Manual 06/11 Standards, formulae, tables Conductors Wiring and cable entries with grommets Cable entry into closed devices is considerably simplified and improved by using cable grommets.
